For those of you that want to disable your pagefile via the registry, just copy and paste the following to a text file, save it with a .reg extension and run. You will need to reboot for the change to take effect. Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management] "PagingFiles"=hex(7):00,00,00,00 If you want to set the pagefile, you'll have to set it manually to get the hex number from your registry. For example, I use the following when setting up new computers. Windows Registry Editor Version 5.00 ; This will set the paging file to C:\pagefile.sys using 4096 as initial and maximum. [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management] "PagingFiles"=hex(7):43,00,3a,00,5c,00,70,00,61,00,67,00,65,00,66,00,69,00,6c,\ 00,65,00,2e,00,73,00,79,00,73,00,20,00,34,00,30,00,39,00,36,00,20,00,34,00,\ 30,00,39,00,36,00,00,00,00,00 We use a lot of old legacy applications along with some new memory hungry applications. This setting works for us even if it isn't ideal. And this is for Windows XP. I always found it odd that Windows XP would set the initial pagefile lower that the recommended initial. But I suppose 10-11 years ago, they never considered we would be running Windows XP with 2 - 4GB memory. Especially since Windows XP 32bit can't use all 4GB of memory due to its own limitation. Call me crazy, but I don't trust Windows to manage my swap file, which is the default in Windows 7. I might try disabling my pagefile at home to see what happens, especially when I play some of my CPU hungry games. ;)
