I am the administrator of my computer and when I attempt to use the system restore facility I recieve the following message:"system restore has been turned off by your administrator. to turn on system restore, contact your system administrator"I have tried right clicking on 'computer' then selecting 'properties' then 'system protection' I am unable to enable this facility as all of the buttons are greyed out.Is there anybody that can offer me any solutions??Many thanks in advanceDave

Are you on a time limited trial version by chance?What version, what license type, etc.?

Hi, It seems that the System Restore related register key was created by certain program or corrupted by virus. First of all, please use your anti-virus program run a full scan and make sure the system is clean, after that, please use Malwarebytes perform another anti-malware scan.http://www.malwarebytes.org/mbam.php Can you turn on system restore now?Turn System Restore on or offhttp://windows.microsoft.com/en-US/windows7/Turn-System-Restore-on-or-off

If the issue persists after scanning the system using anti-virus software as Gordon mentioned, please access Safe Mode (Restart computer, press the F8 key when the boot menu pops up, select [Safe Mode], and boot up) and check if the issue still occurs. If the issue does not occur in Safe Mode, go in to Clean Boot to check the issue. If the issue disappears in the Clean Boot environment, we continue to narrow down which entry is causing the issue.
