I would never change anything in the registry myself, but since you seem comfortable with it, why not reverse what you did yourself and change that registry key/entry back to what it was?
Or use the backup of the registry/key/entry that you made before making any changes.
System Restore may work, but I can't guarantee it.
Not sure why you needed to do that anyway, in the first place. The generally accepted view is to let Windows manage the PF.
I have an emachines desktop with XP, sp3, which I set up to auto clean the page file. I did this by doing the following:
1. Go to start menue2. Click "run"3. Enter "regedit.exe" hit
"enter" or hit "ok"4. Open "HKEY_LOCAL_MACHINE" 5. Open "system"6.
Open "currentcontrolset"7. Open "control"8. Open "Session
Manager"9. Open "Memory management"10. On the right hand side
right click on the value "ClearPageFileAtShutDown" - if there is no
value there right click in the open section and add a DWORD value
and name it "ClearPageFileAtShutdown"11. Change value to "1"12.
I need to reverse this action. Does anyone know how to do this?
