Roll back Windows 10

If you have done the free upgrade to Windows 10 and decide that you want to go back to your previous version of Windows:

Go to Start> Settings> Update & Security> Recovery. Click the Get Started button in the "Go back to Windows 7 (or 8)" section.

*** Windows 10 is no longer available as a free upgrade.  If you do this, and then decide you want to go back to Windows 10, you will have to pay for the upgrade ***
