a. Click Advanced then System Restore to start Microsoft System
Restore:
Microsoft System Restore periodically takes a 'snapshot' of your
system settings and saves them as restore points. In most cases of
hard-to-resolve software problems, you can return to one of these
restore points to get your system running again.
b. Click Reset your PC to start the reset process:
Reset your PC deletes everything on your hard drive, then reinstalls
Windows and all software and drivers that were pre-installed on your
system. If you can access important files on your hard drive, back
them up now. See "Reset your PC from the recovery backup" on
page 54.
c. Click Refresh your PC to start the refresh process:
Refresh your PC will attempt to retain your files (user data) but will
reinstall all software and drivers. Software installed since you
purchased your PC will be removed (except software installed from
the Windows Store). See "Refresh your PC from the recovery
backup" on page 55.
