Clean out the prefetch folder :

Windows XP uses a system called 'prefetch' to organize and preload some of the data necessary for commonly used applications and files. A folder called prefetch is used to store the information the operating system needs to carry out this operation.
After several months of use, the prefetch folder may become quite overloaded with older references to software and files that may no longer be in use.It's a good idea to manually empty the older files out of the prefetch folder every few months or so.
To do this: Navigate to 'c:\windows\prefetch' and delete all .
PF files that are older than a week or two.

Keeping the Windows XP Core in the RAM

If you have 512 MB or more of RAM, you can increase system performance by having the Windows XP 'Core' kept in the RAM instead of paged on the hard disk.

Go to Start -> Run - Type regedit and press enter - On the left hand side tree, navigate to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\

- On the list on the right side, look for an entry called 'DisablePagingExecutive'
- Double click it
- Press 1 on your keyboard
- Click OK
- Exit regedit and reboot the computer

To revert to the default setting, follow the same steps as above, but this time, press 0(zero) instead of 1 on the keyboard.
