If your system has a pretty large amount of RAM (around 1GB or greater), this tip should noticeably boost your system performance. This tip will force the core Windows system to be kept in memory and not paged to disk. To do this:

1.) Go to “Start–>Run” and in the prompt, enter “regedit”. Hit Enter.
2.) Navigate to
“HKEY_LOCAL_MACHINE\SYSTECurrentControlSet\Control\Session
Manager\Memory Management”
3.) In the list of DWORDS on the right, you should see one called “DisablePagingExecutive”.
4.) Right-click on the value and go to “Modify”.
5.) In the “Value” box, change the 0 to a 1 to disable system paging.
6.) Hit okay and restart the computer for the changes to take effect.

This tip works on Windows NT/2000/XP. If you don’t notice a performance increase, you can just change this back to default by doing all of the above steps and switching the value back to 0. Good luck!
