Vista - Restore & Backups

The problem is: When I make a change to my system i.e. new driver, etc I
would like to create a system restore point just in case of a malfunction.
When I try to create a restore point I get this message on my Systems
Property Window under the tab system protection Automatic Restore Point
"Configuration is disabled by group policy" and "Restore Point creation
disabled by group policy." What kind of system protection is that? Is it
protecting my system from my protection? Yes I think so. Is there anyway
to change the group policy on windows Vista Premium since it is unavailable
in the premium version? Wow. This PC belongs to ME not Microsoft.

I have tried to repair my installation. I have lost the ability to create a
restore point and I cannot make a back up. I have tried every solution
offered to me on the NG but nothing works. A re-install seems to be the
only way to me. I'm no expert on this subject but I thought it might be
worth a try.

My back up is supposed to be backed up on My second drive (New
Volume L) and has 91 gb free. Drive L is the only drive enabled for back up
and is far from being full. I have gone to the registry and deleted the
DisableConfig value and I have tried unchecking Hide hidden files and
folders Cleared the Hide protected operating system files, and still cannot
make a backup. I thought Vista Basic was the only system with Group Policy
control. I am using vista Premium. I just don't know what else to do.
