System protection (if turned on) is a feature that allows you to perform a system restore that takes your PC back to an earlier point in time, called a system restore point. This can be handy if your PC isn’t working well and you recently installed an app, driver, or update.
Each restore point contains the necessary information needed to restore the system to the chosen state. Restore points are automatically generated when you install a new app, driver, or Windows update, and generated when you create a restore point manually. Restoring wonâ€™t affect your personal files in your %UserProfile% folder, but it will remove apps, drivers, and updates installed after the restore point was created.
This tutorial will show you how to see a list of all available system restore points in Windows 7, Windows 8, and Windows 10.
