The system restore can revert installed applications, system files, registry and settings from the previously saved computer’s state. I had enable the feature on per drive and partition in Windows 8, and the option is disabled completely after my Surface Pro 3 upgraded to Windows 10 Pro. When I access the system protection tab, select C drive and click configure button, the radio option “Turn on System protection” becomes greyed out.
The problem always happens after the device is updated to Windows 10. The Turn on system protection is greyed out while you are able to access the System Restore panel. If you find that system restore for the Windows drive is turned off and disable, try any of the possible solution.
