When creating an manual or automatic restore point, it takes up to 10 minutes to complete?
If the Windows Management Instrumentation service is stopped, you will experience this delay.
To resolve this behavior:
1. Right-click My Computer and press Manage.
2. Expand Services and Applications.
3. Double-click Windows Management Instrumentation.
4. Change the Startup type to Automatic.
5. If the Service status is Stopped, press Start. If the Service status is Paused, press Resume.
