Please suggest.įrom our experience with Windows 8 upgrades, you're right out of luck. 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. I don't want to Go by installing Windows 8, then upgrading it windows 8.1 then installing all my software again as suggested by Dell. Now I want to activate the Windows 8.1, I have genuine Windows 8 OEM key (found using get_win8key program from BIOS). Now accidentally I updated the product key (invalid one) and windows got deactivated.
Then I upgraded it to windows 8.1 by Windows App Store, everything is fine. I purchased a Dell laptop with windows 8 pre-installed.
