After applying ROG STRIX B550-I GAMING BIOS 3402 - Windows 11 is deactivated

I am also unable to reactivate (possibly a Microsoft server error) - but beware if you're planning on seeing if this BIOS update fixes the 40 series GPU issues...

Windows has reported that your device's hardware has changed. Error code: 0xC004F221

Hi, this error code is indicating to hardware change or major software change, (usually BIOS), the key that was used prior to the change cannot be used as the system is not albe to find and link the key back.

Open a cmd as administrator and share  the output of this command :

slmgr /dlv

If you are not even able to run this command, that will mean you don't have a key.

It is a common issue.  Mine also did that on my B550-A last month  Logged a call with Microsoft and their forums are flooded with users with the same issue.  It is since they blocked the win7/8 to win 11 free upgrade loophole. I had a spare key to use, have not tried my old key to see if it will activate again.
