Thanks for the quick reply

but my problem is not yet solved

i cannot find gpedit.msv in my laptop. I am using Vista Home Premium SP1.
Does my version of Windows have the gpedit.msv option or file?
If it does have, it means my file is destroyed or something wrong has happened

The system restore screen has greyed out the options for me to create my own System Restore points..and it says "Restore point creation disabled by Group policy". But automatic creation of the restore points are made by the system when i install/uninstall or update my laptop.
The problem is that i cannot create my own System Restore Points...
