Windows 8 Desktop back to factory default

If your pc has a mouse, then move it to the top right corner of the screen until a panel containing the Pc Settings appears, then drag down the right edge to expand this desktop strip (called the Charms Bar), then you can click on  the link for Change Pc Settings.  (I'm in Windows 7 now, but I believe that was the way I did it in Windows 8.  I'll have to boot back to Windows 8 to check for sure.)
