Hey guys,
Went from getting my laptop (running Windows 8.1 as the Dell box says) to Windows 7 to Linux and back to 8.1
Now, My issue tonight is after I came back to 8.1 I can't activate it with my OEM key. Ends in FM36R
It says this: That key can't be used to activate this edition of Windows. Please try a different key
However, I installed Windows 8.1 Core (Using the Core generic key for installer) and now it won't let me use the OEM key it just gives me the above error. So what can be done here because I need my Windows copy activated :/
All and any help is greatly appreciated.
