I just upgraded the bios from my MSI motherboard and have the same problem
Error code 0xC004F211, clicking troubleshoot and clicking "I recently changed hardware on this device" also doesn't help.
It then mentions "We can't activate Windows on this device. Try again later."
The windows was updated from Win8Pro to Win10Pro and then Win11Pro.
Also the is nothing happening after making a ticket on Microsoft. You get an confirmation email about the ticket numbering and thats it.
Here some extra info:
Same here I posted a screenshot with error code.
IMPORTANT NOTE - Microsoft itself recommend motherboard BIOS update, to obtain latest security patch!!!
I really can't believe this is happening in 2023 😞
