Okay, now let's say you're in a jam one day because Windowsis misbehaving. Restoring it from the image file may be your only option.
Make sure your backup media is available. Boot up your PC,assuming it's still bootable. In Windows 10, click on the Settings icon> Update & security > Recovery. In the Advanced startup sectionon the right, click on the Restart now button.
At the "Choose an option" window, click on Troubleshoot> Advanced Options > System Image Recovery. From there, follow theprompts in Windows to restore your image file.
If Windows won't boot, then boot up with the system repairdisc. You should be taken to the Choose an option window where you can followthe same steps to restore Windows 10 to a previous and hopefully healthy state
