What is it that you mean by a fast computer? Does it mean fast Internet? Fast games? Fast email? Fast graphics? Fast calculations? Fast windows? Fast downloads? Fast installs? Fast boot-up? Fast shutdown? Each of these things can have a speed of their own? I'll try to answer generally in order to cover my bases.

There are many things that contribute to the speed of a computer. Hardware is the main ingredient for a fast machine. Next comes the Operating System. Software is next in line for contributing to speed. Finally, your internet connection plays a significant role. But this doesn't really answer the question.

The hardware that makes a computer fast is tied to a few main components. First is the processor speed. You might hear about such chips as the Duron, Dual Core, Quad Core, Centrino, Pentium, Athalon64, with such things as 1.8Ghz, 3.5Ghz, 700Mhz. These are all types of chips and various speeds and power at which they operate. Next we have the FSB or Front Side Bus, which determines how fast the data gets to the processor. The faster the data gets to the processor; the faster the processor can begin processing.

If that wasn't enough to spin your head around, there is the speed of the memory. We're talking about actual RAM not virtual memory. Memory is a chip that stores information for the processor, but only while the computer is turned on. When you turn off your computer the memory chip is erased! The faster the memory the more often information can be retrieved and manipulated by the processor.

Then there is the Hard Drive, the place where you put your documents, the operating system, pictures, and everything else that is stored on your computer. When this is slow, the other components have to wait for the information to be retrieved before they'll do anything with it. (Oh, and Don't confuse Hard Drive space with Computer Memory. They are completely different things.)

Here is where the software comes in to the speed of your system. The operating system (i.e., Windows) uses up resources (hardware) on the computer to bring you the Internet, e-mail, movies, entertainment, and photos. Some operating systems use more resources than others, but the bottom line is the newer the operating system the more resources it uses up.

Generally, the more software that gets installed onto a computer the slower the computer will operate. This is not true of all software, but most of the popular ones load a little bit of themselves every time the computer is started. This slows down the computer. Having one or two of these little programs will not slow down your system to any noticeable degree, but when you have a dozen or more, then performance lags.

To counter all these little programs eating up resources, it is best to have as much memory as possible in your computer. Memory should not be confused with what is called Virtual Memory, which is not memory at all. It is actually a file on your Hard Drive that pretends to be memory. If you don't have enough memory, your computer will start using Virtual Memory, and it will slow your computer down. Virtual memory has its uses, but it should be used rarely.

Some of the pitfalls of a slow computer: Most windows computers need some sort of virus protection. Mac, Linux, and BeOS have very few worries in the virus department. Virus protection, at least the popular ones, require more and more resources to protect windows from attacks. Then there's spyware, rootkits, spam, and pop-ups that are a constant bane to windows. A slow computer will be slow to catch and remove these sorts of malware (bad-software). To get better performance, use protection that requires less resources. Symantec, Trend, McAfee are examples of protection that require more resources than is absolutely necessary. There are smaller reliable and free alternatives on the internet, like AVG.

This leads us right to the Internet and how it affects the speed of your computer. Dial-up connections, even on a fast computer, are slow. Too much information needs to pass between your computer and the internet to really be of any use to you. Virus protection updates are almost impossible at dial-up speeds. Dial-up inhibits your access to many webpages, causes delays in email, and limits the quality feedback response required for learning to use your computer and the Internet.

Having a fast Internet connection does not mean you'll have a fast computer. If your computer is slow, a fast Internet connection will not make any real difference in your computers performance.

• Slow Computer + Fast Internet = Slow Computer on the Internet. 
• Fast Computer + Slow Internet = Computer Slowed by the Internet. 
• Faster computer + Faster Internet = Quality experience on the Internet.

Microsoft Windows 7 is already a much more responsive operating system than its predecessors, but there are tweaks and changes you can make to speed up Windows 7 even more. By reading this list and implementing some of the suggestions, you can increase performance in a very short period of time. If you have any further suggestions on how to improve the speed of a Windows 7 PC, please let us know in the comments section so that we can keep updating this list.

1. Boost your RAM
Windows 7 is very efficient at using your memory and adding another stick of RAM can give a big performance boost at very little cost. 4GB is plenty for most 64-bit users, and 3GB is a sensible limit for 32-bit users (mainly due to the memory limitations which you can read about here).
If you do more intensive work such as CAD or video editing then added even more than 4GB RAM may be a sensible idea. However it should be noted that simply adding lots of extra memory will not continue to improve overall performance, the bottleneck depends on other components (such as your CPU and hard drive).

2. Switch to SSD
Using a Solid State Drive is going to provide a performance boost in almost all Windows 7 applications, especially when it comes to boot times. SSD’s have no moving parts and therefore are silent and more energy efficient, with the benefit of much faster access times.
The current generation of mechanical hard drives will be obsolete in the coming years, but for the time being SSDs are quite expensive. If you have the money and a high end system to improve upon, this would be an excellent choice.

3. Install the Correct Version of Windows 7
If you have a high end PC with over 3GB of ram then you should be using the 64-bit version of Windows in most cases. Limitations of 32-bit hardware/software will prevent the use of all the memory a little past the 3GB mark, so you could be wasting the potential of your RAM.
There are many other reasons to choose between 32-bit and 64-bit Windows 7, which are covered in more detail in this article. If you have 64-bit hardware then you may as well make the most of it.

4. Keep your System Drivers Updated
Updating your main system drivers (graphics card, chipset, audio, etc...) will make sure you get the most from any performance enhancements and bug fixes. Graphics card drivers can sometimes provide large boosts to game performance. As Windows 7 is relatively new, driver improvements will be frequent.
Windows Update will provide periodic driver updates for many hardware items, but it is worth bookmarking your graphics driver download page as this will be updated much more frequently and provides the largest potential for a boost in performance.

5. Use Windows ReadyBoost
ReadyBoost is a way of using fast memory drives/cards to provide a high-speed system cache, boosting the performance of your applications without adding any additional physical RAM. ReadyBoost compatible devices have much faster read and write access times than hard disks, and are therefore able to provide speedy buffers for random I/O operations.
This is no substitute for adding more memory to your system, but the ReadyBoost cache can sometimes make a significant difference to application performance. If you have a spare memory stick with suitable performance then this is an easy way to boost system speed. You can read the walkthrough here.

6. Disable Unwanted Startup Applications
Many applications bundle small utilities and unneeded software to your Windows 7 startup list. Often these are just useless tray icons which aren’t necessary and simply slow down your system. Use this guide to prevent these from loading at startup as you may notice a big improvement in boot speed and general usage. Run “msconfig” and view the startup tab to view and change your startup list.
Ideally you should disable any startup entries by uninstalling or configuring the software correctly, as you may find some entries re-appear next time you manually load that application.

7. Disable Unwanted Services
Very similar to the startup items tip, there are some Windows services that are added by 3rd party application that you may not use, as well as some default Windows services that may not be required. Disabling services requires some deeper knowledge, so only change these entries if you are confident in doing so.
Run “services.msc” to view and change the list of services that start on boot, setting ones that aren’t used to “manual start” can improve boot time. There is a full guide on how to do this here.
Black Viper has an excellent list of services which you may not need: http://www.blackviper.com/Windows_7/servicecfg.htm

8. Defrag your System
Windows 7 includes a perfectly functional file defragmentation tool which you can run on an automatic or manual basis to improve access performance. This works by physically re-organising the contents of the disk in to a more logical manor. For example, the data blocks making up a single file will be arranged in the most optimal way (close together). This generally only applies to mechanical drives, so defragging an SSD is not recommended (not least because it could reduce the lifespan of these type of drives).
By default an automatic defrag runs once a week, early in the morning. You should either make sure this is a time when your PC is on but not used heavily, or run it manually every couple of weeks. You can read this guide to see how to run Defrag.

9. Use Automatic Logon
If you are the only person with access to your PC and feel you don’t need to secure it with a password then you can use automatic logon to save a few seconds. This will boot right to your desktop without any need to enter a password and wait for loading. Please be aware that anyone could use your computer by doing this, so consider the security aspect first.
There is a full walkthrough on how to enable this on your system here.

10. Clean up Old Files
Windows 7 has a system cleanup tool which you can use to recover free space on your hard drive. This is an easy way to remove temporary files, old installation data and log files which accumulate over time. You can read the guide on how to run this here.
There are also some free 3rd party utilities that can clean other types of data. One recommended choice would be CCleaner as this is highly unlikely to do any harm to your system, but provides a quick and easy way to clean temp files from a wide range of 3rd party programs.

11. Uninstall Unnecessary Software
If you had Windows 7 pre-installed on a new PC there is a good chance that you had several useless applications bundled with the operating system. If you aren’t going to use them, then you may as well remove them. Common examples are ISP trials , toolbar applications (Yahoo, Google), time limited shareware software (often DVD burner or Photo applications such as Sonic, Roxio and Corel).
Users can take a look at the system tray to see if there is any software running in the background that you rarely or never use. Uninstalling this clutter has the potential to speed up your system if it has processes that run in the background.
You can load up the “add/remove programs” tool and browse the list to see which applications are never used. If you are unlikely to use them again in the future, uninstall it and save some disk space. If you are unsure how to do this, please follow our uninstallation guide.

12. Change Windows 7 visual effects
Windows 7 includes additional eye-candy in the form of shadows, window transparency and other extras. Adding these graphical features does require a small amount of extra power, which most modern computers can handle easily. However, older PCs may wish to turn off some effects to improve overall performance.
This guide shows you how you can change the options manually or allow Windows to adjust the settings based on your hardware specifications. If you are trying to gain the maximum possible performance then you can disable all these visual effects.

13. Make use of Keyboard Shortcuts
Using keyboard shortcuts won’t speed up Window 7 per-se, however it will speed up your interaction with the OS which has the same overall effect.
We have compiled a list which includes lots of handy shortcut keys for things, some of which you will no doubt already know about (such as CTRL+C for “copy” and Windows Key + R for “run”), but there are lots of new additions to Windows 7.

14. Disable Search Indexing
This is a feature whereby Windows 7 will scan your hard drive and create an index of many of the files, e-mails and media items on your PC. When you want to perform a search, this will greatly speed up the result retrieval in most cases. However, building and updating this index can slow your PC down when it is in progress.
If you know that you are unlikely to ever use the search feature or want advanced control over your file searches then you may as well disable the index. This will prevent extra hard drive activity during day to day computing. You can read this guide to find out more.
Most users will not want to disable search indexing as it will also take out the start menu search box - this tip is mainly for those wishing to gain every ounce of extra performance.

15. Disable Gadgets
Windows 7 uses customisable gadgets which you can place anywhere on the desktop, unlike the sidebar previously seen in Windows Vista. Some of these gadgets are quite active and take up a small portion of system resources to display and update. Turning off all gadgets will speed up your system that little bit more.
You can close all of the gadgets so that none display, of if you wish to go a step further, the entire Windows 7 gadgets platform can be disabled by following this article.

16. Choose High Performance Power Plan
This tip relates more to mobile computing (i.e. laptops, netbooks and tablet PCs), as the power options can change when you are using battery or mains power. Often it makes sense to choose an energy-saving plan (hence lower performance) when you are using your device on the move, however you should make sure that you are running a high-performance plan when running from mains power.
Advanced power plan settings allow you to adjust a wide range of hardware power-saving/performance features. You can even change the min/max CPU usage, which can have a huge performance hit when set incorrectly. This article shows you how to alter the power plan settings.

17. Use Hibernate/Sleep Mode
Effective use of the hibernation and sleep modes will allow you to resume working on your PC very quickly, instead of having to wait for Windows 7 to boot up again. The hibernate feature will save your current system memory to disk and power down the machine, which means that your last session is resumed within moments of powering the machine back up. This is a great way to keep documents and other work open if you will be continuing work on them the next day. You can find out how to enable hibernation mode on your PC here.
Sleep mode does not power down your machine, but it puts the computer hardware into a low-power state. If you are going to leave your machine for a few hours, this is a good way to maintain and quickly resume your system state without power your machine down. You can put Windows 7 in to sleep mode automatically (by configuring this in your power plan), or manually by clicking on the corresponding option on the shutdown menu.

18. Use an efficient Anti-Virus package
Anti-Virus and Anti-Malware packages can contribute the performance drag of a PC, which some users dislike enough to go without real-time security software (although this is strongly not recommended for most users!). A good way to achieve a sensible balance between protection and speed is to use an efficient anti-virus package that has a low resource footprint.
You can use the AV Comparatives website to view benchmarks and performance testing on all of the major anti-virus applications. This should help you choose a security package that performs well and suits your system power. We also have a listing of free anti-virus packages for Windows 7 that may be of use.

19. Run periodic Anti-Spyware scans
Although many tech-savvy readers will have some sort of anti-malware scanner on their computer, it is worth reiterating this for those that don’t yet use it. I wouldn’t recommend relying on this software, but it can be a useful tool if you unintentionally end up installing spyware software (often in the form of near-useless free downloads).
MBAM is one of the more highly rated applications, and it’s worth running once in a while to see if anything prompts further investigation.

There are a number of apps in the Apple App Store that let you control your computer or a specific software using your iPhone. You can use your iPhone as a mouse, remote control iTunes with it and do a whole lot more. Such apps are fun to use simply by the virtue of the “awesomeness” factor.
We are going to be using the iPhone as a VNC server. Apple, of course wouldn’t allow such a feat to be accomplished on their cherished device, so you won’t find any such application in the Apple App Store. However, you might be aware that another very popular platform exists where you can get free and paid apps that you won’t find on Apple’s App Store. I am talking about Cydia.

Before we proceed any further I must mention a disclaimer. Jailbreaking has recently been legalized in the United States but you might want to check your local laws if you are outside the United States. Also keep in mind that jailbreaking will void your Apple warranty.

We need a jailbroken device for Cydia and we need Cydia for Veency which is the app that lets you connect to your iPhone remotely via VNC and thus control it from your computer. Veency is of course not the only app that jailbroken device owners might be interested in. There are lots of them available via Cydia that let you tweak your iPhone in ways no other app on the App Store would let you do.

Jailbreaking is easier than ever before with the latest app called jailbreakme. The actual process is however beyond the scope of our discussion here.

Installing Veency

• Open Cydia on your iPhone. Let it download the packages and do its thing. Now go to search and look for Veency.

• Click or tap on Veency. You will be able to see details of the Veency Package. Browse through them to know more about it.
• Once satisfied you can click the Install button towards the top right.
• Cydia will ask for confirmation before proceeding and show you a summary of what will be changed

• Confirm and Veency will be downloaded and installed on your iPhone.

Using Veency

From a configuration point of view you only need to ensure that WiFi is switched on your iDevice before you can access it remotely. You will also need to know the IP address that gets assigned to your device. You already know this if you assigned it manually.

Else you can find the IP address assigned to your device by visiting Settings > General. Then click on the blue arrow next to WiFi network name and you should find your settings listed there.

Accessing Remotely

Your iDevice now has a VNC server installed. So you should be able to connect easily using a VNC client. We have covered a number of them before. TightVNC stands out if you are on Windows. Download and install it from here. A portable version is also available if you are so inclined. Once that is out of the way, fire it up.

Next up you need to enter the IP address we determined above. And confirm the VNC request:

Once you are connected you will be able to use your iPhone remotely via your computer.

This is especially handy when typing long messages or accessing your iPhone in another room. There are certain downsides as well. Since you are using this with the mouse you won’t be able to replicate all the ground breaking gestures that make the iPhone so special.

Social networking websites like MySpace, Facebook, Twitter, and Windows Live Spaces are services people can use to connect with others to share information like photos, videos, and personal messages.

As the popularity of these social sites grows, so do the risks of using them. Hackers, spammers, virus writers, identity thieves, and other criminals follow the traffic.

Read these tips to help protect yourself when you use social networks.

1. Use caution when you click links that you receive in messages from your friends on your social website. Treat links in messages on these sites as you would links in email messages. (For more information, see Approach links in email with caution and Click Fraud: Cybercriminals want you to 'like' it.)
2. Know what you've posted about yourself. A common way that hackers break into financial or other accounts is by clicking the "Forgot your password?" link on the account login page. To break into your account, they search for the answers to your security questions, such as your birthday, home town, high school class, or mother's middle name. If the site allows, make up your own password questions, and don't draw them from material anyone could find with a quick search. For more information, see:
   • What was the name of your first pet?
   • What is screen scraping?
   • Take charge of your online reputation
3. Don't trust that a message is really from who it says it's from. Hackers can break into accounts and send messages that look like they're from your friends, but aren't. If you suspect that a message is fraudulent, use an alternate method to contact your friend to find out. This includes invitations to join new social networks. For more information, see Scammers exploit Facebook friendships.
4. To avoid giving away email addresses of your friends, do not allow social networking services to scan your email address book. When you join a new social network, you might receive an offer to enter your email address and password to find out if your contacts are on the network. The site might use this information to send email messages to everyone in your contact list or even everyone you've ever sent an email message to with that email address. Social networking sites should explain that they're going to do this, but some do not.
5. Type the address of your social networking site directly into your browser or use your personal bookmarks. If you click a link to your site through email or another website, you might be entering your account name and password into a fake site where your personal information could be stolen. For more tips about how to avoid phishing scams, see How to reduce the risk of online fraud.
6. Be selective about who you accept as a friend on a social network. Identity thieves might create fake profiles in order to get information from you.
7. Choose your social network carefully. Evaluate the site that you plan to use and make sure you understand the privacy policy. Find out if the site monitors content that people post. You will be providing personal information to this website, so use the same criteria that you would to select a site where you enter your credit card.
8. Assume that everything you put on a social networking site is permanent. Even if you can delete your account, anyone on the Internet can easily print photos or text or save images and videos to a computer.
9. Be careful about installing extras on your site. Many social networking sites allow you to download third-party applications that let you do more with your personal page. Criminals sometimes use these applications to steal your personal information. To download and use third-party applications safely, take the same safety precautions that you take with any other program or file you download from the web. For more information, see Before you download files, help protect your computer.
10. Think twice before you use social networking sites at work. For more information, see Be careful with social networking sites, especially at work.
11. Talk to your kids about social networking. If you're a parent of children who use social networking sites, see How to help your kids use social websites more safely.

WINDOWS XP TWEAKS

-----------
STARTUP
-----------


Windows Prefetcher
******************
[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Session Manager \ Memory Management \ PrefetchParameters]

Under this key there is a setting called EnablePrefetcher, the default setting of which is 3. Increasing this number to 5 gives the prefetcher system more system resources to prefetch application data for faster load times. Depending on the number of boot processes you run on your computer, you may get benefits from settings up to 9. However, I do not have any substantive research data on settings above 5 so I cannot verify the benefits of a higher setting. This setting also may effect the loading times of your most frequently launched applications. This setting will not take effect until after you reboot your system.


Master File Table Zone Reservation
**********************************
[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ FileSystem]

Under this key there is a setting called NtfsMftZoneReservation, the default setting of which is 1. The range of this value is from 1 to 4. The default setting reserves one-eighth of the volume for the MFT. A setting of 2 reserves one-quarter of the volume for the MFT. A setting of 3 for NtfsMftZoneReservation reserves three-eighths of the volume for the MFT and setting it to 4 reserves half of the volume for the MFT. Most users will never exceed one-quarter of the volume. I recommend a setting of 2 for most users. This allows for a "moderate number of files" commensurate with the number of small files included in most computer games and applications. Reboot after applying this tweak.


Optimize Boot Files
*******************
[HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Dfrg \ BootOptimizeFunction]

Under this key is a text value named Enable. A value of Y for this setting enables the boot files defragmenter. This setting defragments the boot files and may move the boot files to the beginning (fastest) part of the partition, but that last statement is unverified. Reboot after applying this tweak.

Optimizing Startup Programs [msconfig]
**************************************

MSConfig, similar to the application included in Win9x of the same name, allows the user to fine tune the applications that are launched at startup without forcing the user to delve deep into the registry. To disable some of the applications launched, load msconfig.exe from the run command line, and go to the Startup tab. From there, un-ticking the checkbox next to a startup item will stop it from launching. There are a few application that you will never want to disable (ctfmon comes to mind), but for the most part the best settings vary greatly from system to system.

As a good rule of thumb, though, it is unlikely that you will want to disable anything in the Windows directory (unless it's a third-party program that was incorrectly installed into the Windows directory), nor will you want to disable anything directly relating to your system hardware. The only exception to this is when you are dealing with software, which does not give you any added benefits (some OEM dealers load your system up with software you do not need). The nice part of msconfig is that it does not delete any of the settings, it simply disables them, and so you can go back and restart a startup application if you find that you need it. This optimization won't take effect until after a reboot.

Bootvis Application
*******************
The program was designed by Microsoft to enable Windows XP to cold boot in 30 seconds, return from hibernation in 20 seconds, and return from standby in 10 seconds. Bootvis has two extremely useful features. First, it can be used to optimize the boot process on your computer automatically. Second, it can be used to analyze the boot process for specific subsystems that are having difficulty loading. The first process specifically targets the prefetching subsystem, as well as the layout of boot files on the disk. When both of these systems are optimized, it can result in a significant reduction in the time it takes for the computer to boot.

Before attempting to use Bootvis to analyze or optimize the boot performance of your system, make sure that the task scheduler service has been enabled – the program requires the service to run properly. Also, close all open programs as well – using the software requires a reboot.

To use the software to optimize your system startup, first start with a full analysis of a fresh boot. Start Bootvis, go to the Tools menu, and select next boot. Set the Trace Repetition Settings to 2 repetitions, Start at 1, and Reboot automatically. Then set the trace into motion. The system will fully reboot twice, and then reopen bootvis and open the second trace file (should have _2 in the name). Analyze the graphs and make any changes that you think are necessary (this is a great tool for determining which startup programs you want to kill using msconfig). Once you have made your optimizations go to the Trace menu, and select the Optimize System item. This will cause the system to reboot and will then make some changes to the file structure on the hard drive (this includes a defragmentation of boot files and a shifting of their location to the fastest portion of the hard disk, as well as some other optimizations). After this is done, once again run a Trace analysis as above, except change the starting number to 3. Once the system has rebooted both times, compare the charts from the second trace to the charts for the fourth trace to show you the time improvement of the system's boot up.

The standard defragmenter included with Windows XP will not undo the boot optimizations performed by this application.



-----------------------------------
General Performance Tweaks
-----------------------------------


IRQ Priority Tweak
******************
[HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Control \ PriorityControl]

You will need to create a new DWORD: IRQ#Priority (where # is the number of the IRQ you want to prioritize) and give it a setting of 1. This setting gives the requisite IRQ channel priority over the other IRQs on a software level. This can be extremely important for functions and hardware subsystems that need real-time access to other parts of the system. There are several different subsystems that might benefit from this tweak. Generally, I recommend giving either the System CMOS or the video card priority. The System CMOS generally has an IRQ setting of 8, and giving it priority enhances the I/O performance of the system. Giving priority to the video card can increase frame rates and make AGP more effective.

You can give several IRQs priority, but I am not entirely certain how the system interacts when several IRQs are given priority – it may cause random instabilities in the system, although it is more likely that there's a parsing system built into Windows XP to handle such an occurrence. Either way, I would not recommend it.

QoS tweak
*********
QoS (Quality of Service) is a networking subsystem which is supposed to insure that the network runs properly. The problem with the system is that it eats up 20% of the total bandwidth of any networking service on the computer (including your internet connection). If you are running XP Professional, you can disable the bandwidth quota reserved for the system using the Group Policy Editor [gpedit.msc].

You can run the group policy editor from the Run command line. To find the setting, expand "Local Computer Policy" and go to "Administrative Templates" under "Computer Configuration." Then find the "Network" branch and select "QoS Packet Scheduler." In the right hand box, double click on the "Limit Reservable Bandwidth." From within the Settings tab, enable the setting and then go into the "Bandwidth Limit %" and set it to 0%. The reason for this is that if you disable this setting, the computer defaults to 20%. This is true even when you aren't using QoS.

Free Idle Tasks Tweak
*********************

This tweak will free up processing time from any idle processes and allow it to be used by the foreground application. It is useful particularly if you are running a game or other 3D application. Create a new shortcut to "Rundll32.exe advapi32.dll,ProcessIdleTasks" and place it on your desktop. Double-click on it anytime you need all of your processing power, before opening the application.

Windows Indexing Services
Windows Indexing Services creates a searchable database that makes system searches for words and files progress much faster – however, it takes an enormous amount of hard drive space as well as a significant amount of extra CPU cycles to maintain the system. Most users will want to disable this service to release the resources for use by the system. To turn off indexing, open My Computer and right click on the drive on which you wish to disable the Indexing Service. Enter the drive's properties and under the general tab, untick the box for "Allow the Indexing Service to index this disk for fast file searching."

Priority Tweak
**************
[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ PriorityControl]

This setting effectively runs each instance of an application in its own process for significantly faster application performance and greater stability. This is extremely useful for users with stability problems, as it can isolate specific instances of a program so as not to bring down the entire application. And, it is particularly useful for users of Internet Explorer, for if a rogue web page crashes your browser window, it does not bring the other browser windows down with it. It has a similar effect on any software package where multiple instances might be running at once, such as Microsoft Word. The only problem is that this takes up significantly more memory, because such instances of a program cannot share information that is in active memory (many DLLs and such will have to be loaded into memory multiple times). Because of this, it is not recommended for anyone with less than 512 MB of RAM, unless they are running beta software (or have some other reason for needing the added stability).

There are two parts to this tweak. First is to optimize XP's priority control for the processes. Browse to HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ PriorityControl and set the "Win32PrioritySeparation" DWORD to 38. Next, go into My Computer and under Tools, open the Folder Options menu. Select the View tab and check the "Launch folder windows in separate process" box. This setting actually forces each window into its own memory tread and gives it a separate process priority.

Powertweak application
**********************
xxx.powertweak.com

Powertweak is an application, which acts much like a driver for our chipsets. It optimizes the communication between the chipset and the CPU, and unlocks several "hidden" features of the chipset that can increase the speed of the system. Specifically, it tweaks the internal registers of the chipset and processor that the BIOS does not for better communication performance between subsystems. Supported CPUs and chipsets can see a significant increase in I/O bandwidth, increasing the speed of the entire system. Currently the application supports most popular CPUs and chipsets, although you will need to check the website for your specific processor/chipset combo – the programmer is working on integrating even more chipsets and CPUs into the software.

Offload Network Task Processing onto the Network Card
*****************************************************
[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Tcpip \ Parameters]

Many newer network cards have the ability of taking some of the network processing load off of the processor and performing it right on the card (much like Hardware T&L on most new video cards). This can significantly lower the CPU processes needed to maintain a network connection, freeing up that processor time for other tasks. This does not work on all cards, and it can cause network connectivity problems on systems where the service is enabled but unsupported, so please check with your NIC manufacturer prior to enabling this tweak. Find the DWORD "DisableTaskOffload" and set the value to 0 (the default value is 1). If the key is not already available, create it.

Force XP to Unload DLLs
***********************
[HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer]
"AlwaysUnloadDLL"=dword:00000001

XP has a bad habit of keeping dynamic link libraries that are no longer in use resident in memory. Not only do the DLLs use up precious memory space, but they also tend to cause stability problems in some systems. To force XP to unload any DLLs in memory when the application that called them is no longer in memory, browse to HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer and find the DWORD "AlwaysUnloadDLL". You may need to create this key. Set the value to 1 to force the operating system to unload DLLs.

Give 16-bit apps their own separate processes
*********************************************
[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ WOW]
"DefaultSeparateVDM"="Yes"

By default, Windows XP will only open one 16-bit process and cram all 16-bit apps running on the system at a given time into that process. This simulates how MS-DOS based systems viewed systems and is necessary for some older applications that run together and share resources. However, most 16-bit applications work perfectly well by themselves and would benefit from the added performance and stability of their own dedicated resources. To force Windows XP to give each 16-bit application it's own resources, browse to HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ WOW and find the String "DefaultSeparateVDM". If it is not there, you may need to create it. Set the value of this to Yes to give each 16-bit application its own process, and No to have the 16-bit application all run in the same memory space.

Disable User Tracking
*********************
[HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer]
"NoInstrumentation"=dword:00000001

The user tracking system built into Windows XP is useless to 99% of users (there are very few uses for the information collected other than for a very nosy system admin), and it uses up precious resources to boot, so it makes sense to disable this "feature" of Windows XP. To do so, browse to HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer and find the DWORD "NoInstrumentation". You may need to create this key if it is not there. The default setting is 0, but setting it to 1 will disable most of the user tracking features of the system.

Thumbnail Cache
***************
[HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Advanced]
"DisableThumbnailCache"=dword:00000001

Windows XP has a neat feature for graphic and video files that creates a "thumbnail" of the image or first frame of the video and makes it into an oversized icon for the file. There are two ways that Explorer can do this, it can create them fresh each time you access the folder or it can load them from a thumbnail cache. The thumbnail caches on systems with a large number of image and video files can become staggeringly large. To disable the Thumbnail Cache, browse to HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Advanced and find the DWORD "DisableThumbnailCache". You may need to create this key. A setting of 1 is recommended for systems where the number of graphic and video files is large, and a setting of 0 is recommended for systems not concerned about hard drive space, as loading the files from the cache is significantly quicker than creating them from scratch each time a folder is accessed.

sebenarnya udah lama,tapi Mungkin dari anda penasaran mendengar judulnya “Unlocking GeForce FX to Quadro”. Apa itu??, tenang….disini saya akan mengutarakan dan menjabarkannya dengan bahasa yang guampang dimengerti…….ok tanpa panjang X lebar kita mulai aja…….

Nah, yang dimaksud Unlocking GeForce FX to Quadro adalah meng-Convert GeForce FX ke Quadro secara Softmod (modifikasi software driver) dengan Rivatuner. Caranya :

Sebelum ber-Overclocking Ria selalu INGAT kata-kata ini :

YOU DO ALL MODIFICATIONS AT YOUR OWN RISK!!!!

(Rusak Tanggung Dewe/RTD)

Perhatikan Langkah-langkah berikut ini :

• @ - Download driver VGA nvidia di www.nvidia.com (Saya menggunakan driver 93.71)
• @ - Download RivaTuner 2.0 atau lebih dan SoftQuadro4 patch pack di www.guru3d.com
• @ - Install RivaTuner di PC anda dan Extract Softquadro4 didirektori Riva Tuner.
• @ - Jalankan RivaTuner, klik Power User. Klik tombol Open Patch Script. masuk di RivaTuner/PatchScripts/NVIDIA/NVStrap antiprotection, pilih NVStrap antiprotection w2k.rts dan klik Open. lalu klik Continue, lalu cari dimana folder driver Nvidia anda diletakkan dan cari nv4_mini.sys, klik Open, Ok, Close.
• @ - Lagi dari Power User , klik Open Patch Script. Kali ini masuklah ke RivaTuner/PatchScripts/NVIDIA/SoftQuadro4, pilih SoftQuadro4 w2k.rts lalu klik open. Klik Continue and lalu masuklah ke folder driver Nvidia seperti pada langkah 4 dan cari nv4_mini.sys, klik Open, Ok, Close.
• @ - Klik Main. Klik tombol kotak kecil bertuliskan Customize untuk melihat diskripsi dari VGA anda (di PC saya "128-bit AGP NV34 with 256MB DDR memory Customize...). Klik tombol di sebelah kiri (Customize low level system settings). Pilih NVStrap driver. dibawah, Klik tombol Install, dan Scroll dgn panah atas bawah pilih Professional Quadro capabilities pilih force on. Klik OK. Setelah proses Ini anda diminta merestart. Tapi Jangan direstart dulu.
• @ - Keluar dari RivaTuner dan, dari control panel->add/remove programs, hapus semua driver nvidia anda. Sekarang saatnya merestart komputer tercinta anda…….

@ Selama booting, layar PC anda akan menampilkan resolusi tampilan 640x480. Lalu akan mendeteksi adanya VGA baru, sekarang saatnya install VGA anda secara manual dengan driver VGA yang telah termodifikasi (ter-patch) tadi.

Setelah langkah-langkah panjang tersebut, Selamat!!!YOU'RE DONE. Dan lihat sekarang pada driver propertis, VGA anda telah berubah menjadi Quadro,selain itu anda dapat merubah-ubah setting OpenGL yang ada di Quadro tersebut. Langkah-langkah diatas telah saya coba dan BERHASIL!!!. Selanjutnya terserah anda mau coba atau tidak. Tapi INGAT (YOU DO ALL MODIFICATIONS AT YOUR OWN RISK!!!!). OK and Good Luck for you……
