System Restore is a way to undo system changes by using restore points to return your system files and settings to an earlier point in time without affecting personal files of users. System Restore uses a feature called system protection that regularly creates and saves information about your PC's drivers, programs, registry, system files, and settings as restore points.But it's hard to use System Restore if it's turned off.
If you are having recent problems with Windows 10, then you could do a System Restore to restore Windows back to an earlier point in time, called a restore point.
And Windows 10 tends to turn off System Restore every time you do an upgrade, e.g. Creators Update.
After you upgrade Windows 10 press the Windows key and type "Create a restore point".
Click on it and you'll see this dialog.
Yep. System Restore is turned off. Click on "Configure".
Click on "Turn on system protection" and drag the "Max Usage" over to something 5% or greater.
Click on "OK" and you're done. And safer.
