You upgraded to Windows 8, but didn’t have a previous version of Windows installed (error 0xC004F061)

If you see error 0xC004F061 when you try to activate Windows 8, it means that you’re using a product key for an upgrade version of Windows 8 and a previous version of Windows wasn’t on your PC when Windows 8 was installed. To install an upgrade version of Windows 8, you must already have Windows 7, Windows Vista, or Windows XP installed on your PC.

If you formatted the drive before the upgrade version of Windows 8 was installed, you won’t be able to use your upgrade product key to activate Windows 8.
