This policy setting allows you to prevent Windows from creating a system restore point during device activity that would normally prompt Windows to create a system restore point. Windows normally creates restore points for certain driver activity such as the installation of an unsigned driver. A system restore point enables you to more easily restore your system to its state before the activity. If you enable this policy setting Windows does not create a system restore point when one would normally be created.If you disable or do not configure this policy setting Windows creates a system restore point as it normally would.
At least Windows Vista
