the system cache is always being used, it does not matter how mush or how little ram is being used. To have windows stored on ram to make the system run alot faster, and not have to go the harddrive heres a hack for you.
While Windows2k and WInXP manage its memory much better then the Win9x based operating systems, you can make both the actual Win2k or XP OS run more efficiently by keeping all of its code in system memory (since it's the most used program) rather than in a HDD swap file.
Go to Start -> Run and type regedit. From there follow this path. HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Control -> Session Manager -> Memory Management. Right click on the DisablePagingExecutive DWORD value, change its value to 1, save and reboot.
Now Win2k and WinXP will stay in your system memory instead of going into the HDD swap file. Please note, you must have at least 512MB of system memory otherwise you'll notice a slowdown in performance!
