Many web sites show this tweak. It loads the Windows Kernel directly into Ram memory rather than the slower Virtual Memory on the HD. You have to have enough Ram to do this. I would suggest at least 4 Gb. Some sites state you can do this with less Ram, but a lot depends on how much multi-tasking you do and how big your opens apps are.
Make a backup of your registry before attempting any change in the registry. (Be very careful in the registry as you can cause a lot of damage here that can render your PC unbootable) See this thread for instructions.
Go to Start>Run. Type ‘Regedit‘ and hit enter.
In the registry editor go to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Memory Management\DisablePagingExecutive
Double click the DisablePagingExecutive and change the value to “1“.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Memory Management\LargeSystemCache
Double click the LargeSystemCache and change the value to “1“.
Close the editor and restart Windows. Your computer should perform faster now.
