Q. How can I stop a restore point from being created every time I install a new driver in Windows Vista and later?

A. Normally, when a new driver is installed a system restore point is created. This can take a significant amount of time. If you're an experienced user and don't want this restore point automatically created, you can disable it using the Group Policy setting

Computer Configuration\Policies\Administrative Templates\System\Device Installation\Prevent creation of a system restore point during device activity

This would prompt creation of a restore point, so set it to Enabled.
