The Windows activation key is not valid.
The Windows activation key is not valid.
I changed my system bios last night and now the message says Windows isn't activated. I used the key I bought when I built the PC, but it shows as invalid. I've updated the bios several times since February without any problems. Could there be another reason for this issue? The key I got from Whokeys has been working well until today.
there is an issue with the windows activation servers, so it's likely your issue will resolve itself in the coming weeks.
