I purchased a Dell laptop with windows 8 pre-installed. Then I upgraded it to windows 8.1 by Windows App Store, everything is fine. Now accidentally I updated the product key (invalid one) and windows got deactivated. Now I want to activate the Windows
8.1, I have genuine Windows 8 OEM key (found using get_win8key program). I don't want to Go by installing Windows 8, then upgrading it windows 8.1 then installing all my software again. As at the time of upgrade It didn't ask for product key and I assume that
program read the key from BIOS itself and Windows 8.1 is activated, so there should be equivalent key to be used to activate windows 8.1 again. Please suggest.
