Ich hab noch was gefunden:
Zitat von

To restore System Restore, click Start > Run and type regedit and press [Enter]. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Win dows NT\SystemRestore and delete "DisableConfig" and "DisableSR", exit Registry Editor and restart Windows.
Vielleicht hilft es.
