I have a laptop running Windows 7 Ultimate using a key from my MSDN subscription. Long story short, subscription expired, and all keys I had requested got flagged as not genuine and thus the laptop started getting the error messages for not being genuine.
I just bought a license through Newegg for ~$182 for an OEM edition. I tried entering the key but I get an error message that it's invalid. Thus I am not sure what to do. I don't want to reformat the whole thing just to get the key to work... so I'm hoping someone can suggest how I can get it to work.
I've gone through the "Computer" screen to change and I've tried the CMD method too, both of which failed.
Anyway, thanks in advance!
