trick to manually change the size of the virtual memory paging file

You must be logged on as an administrator or as a member of the Administrators group to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure.
1. Click Start, click Run, and then type sysdm.cpl in the Open box.
2. Click the Advanced tab, and then click Settings under Performance.
3. Click the Advanced tab, and then click Change under Virtual memory.
4. Under Drive [Volume Label], click the drive that contains the paging file that you want to change.
5. Under Paging file size for selected drive, click Custom size, type a new paging file size in megabytes (MB) in the Initial size (MB) or Maximum size (MB) box, and then click Set.
If you decrease the size of either the initial or maximum paging file settings, you must restart your computer to see the effects of those changes. When you increase the paging file size, you typically do not have to restart your computer.

Notes
• To have Windows select the best paging file size, click System managed size. The recommended minimum size is equivalent to 1.5 times the RAM on your computer, and 3 times that figure for the maximum size. For example, if you have 256 MB of RAM, the minimum size is 384 MB, and the maximum size is 1152 MB.
• For best performance, do not set the initial size to less than the minimum recommended size under Total paging file size for all drives. The recommended size is equivalent to 1.5 times the RAM on your computer. It is good practice to leave the paging file at its recommended size. However, you may increase its size if you frequently use programs that use much memory.
• To delete a paging file, set both the initial size and the maximum size to zero, or click No paging file. We strongly recommend that you do not disable or delete the paging file.
How to manually optimize the memory usage
You can optimize your computer's memory usage. If you use your computer primarily as a workstation instead of as a server, you can devote more memory to your programs. Your programs will work faster and your system cache size will remain the default size that came with Windows XP. You can also set aside more computer memory for a larger system cache if your computer is used primarily as a server, or if you use programs that require a larger cache.
1. Click Start, click Run, and then type sysdm.cpl in the Open box.
2. Click the Advanced tab, and then click Settings under Performance.
3. Click the Advanced tab, and then use one of the following methods under Memory usage:
• Click Programs if you use your computer primarily as a workstation instead of as a server. This option allocates more memory to your programs.
• Click System cache if your computer is used primarily as a server or if you use programs that use a larger cache.

how to set performance options in Windows XP

How to manually manage processor time Windows manages system processing. Windows can allocate tasks between processors and manage multiple processes on a single processor. However, you can set Windows to allocate more processor time to the program that you are currently running. The added processor time causes programs to respond more quickly. Or, if you have background programs such as printing or disk backup that you want to run while you work, you can have Windows share processor resources equally between background and foreground programs.

Note You must be logged on as an administrator to the local computer or have the correct network credentials to make certain changes in System.

How to manually change the performance of foreground and background programs
1. Click Start, click Run, and then type sysdm.cpl in the Open box.
2. Click the Advanced tab, and then click Settings under Performance.
3. Click the Advanced tab, and then use one of the following methods under Processor scheduling:
• Click Programs to assign more processor resources to the foreground program than the background program.
• Click Background services to assign equal amounts of processor resources to all programs.
Notes
• If you click Programs, the foreground program runs more smoothly and responds more quickly. If you want a background task such as a Backup utility to run faster, click Background services.
• The Programs option allocates short, variable time slices (quanta) to running programs, and the Background services option assigns long, fixed quanta.

how to Connect a drive from My Computer or Windows Explorer

1.	To connect a drive from My Computer, click Start, right-click My Computer, and then click Explore. To connect a drive from Windows Explorer, right-click Start, and then click Explore.

Free up disk space

By freeing disk space, you can improve the performance of your computer. The Disk Cleanup tool helps you free up space on your hard disk. The utility identifies files that you can safely delete, and then enables you to choose whether you want to delete some or all of the identified files.
Use Disk Cleanup to:

•	Remove temporary Internet files.
•	Remove downloaded program files (such as Microsoft ActiveX controls and Java applets).
•	Empty the Recycle Bin.
•	Remove Windows temporary files.
•	Remove optional Windows components that you don't use.
•	Remove installed programs that you no longer use.

Tip: Typically, temporary Internet files take the most amount of space because the browser caches each page you visit for faster access later.

To use Disk Cleanup

1.	Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Cleanup. If several drives are available, you might be prompted to specify which drive you want to clean.
2.	In the Disk Cleanup for dialog box, scroll through the content of the Files to delete list. Choose the files that you want to delete.
3.	Clear the check boxes for files that you don't want to delete, and then click OK.
4.	When prompted to confirm that you want to delete the specified files, click Yes.

After a few minutes, the process completes and the Disk Cleanup dialog box closes, leaving your computer cleaner and performing better.

How to decide what data to back up

There are many ways you can unintentionally lose information on a computer. A child playing the keyboard like a piano, a power surge, lightning, floods. And sometimes equipment just fails. If you regularly make backup copies of your files and keep them in a separate place, you can get some, if not all, of your information back in the event something happens to the originals on your computer. Deciding what to back up is highly personal. Anything you cannot replace easily should be at the top of your list. Before you get started, make a checklist of files to back up. This will help you determine what to back up, and also give you a reference list in the event you need to retrieve a backed-up file. Here are some file suggestions to get you started: • Bank records and other financial information • Digital photographs • Software you purchased and downloaded from the Internet • Music you purchased and downloaded from the Internet • Personal projects • Your e-mail address book • Your Microsoft Outlook calendar • Your Internet Explorer bookmarks If you haven't already decided where you want to store your backup copies—external hard disk drive, CDs, DVDs, or some other storage format—and you want to know more about your options
