The PC had been activated for about two years. It only deactivated immediately after updating the BIOS on my Biostar B450MHP. The Activation Troubleshooter says it cannot find any devices linked to my Microsoft account for reactivation, even though this is the only Microsoft account I've ever used and the PC still appears in my Microsoft devices. I also had a laptop which is now broken, also activated windows there just by signing in with my microsoft account
Windows activation issue
So i updated my bios and after tried to activate my windows(windows 11), went to trouble shoot and it said it didnt find any of my devices. Error code 0xC004F211. I do have an account with a windows key, hell it was active a few days ago before my bios got updated. I've tried everything i could think of, every solution i could scrounge up from the internet, i just geniunely need to talk to a microsoft support person and i've been trying for hours, its impossible. Please can a microsoft support person help.
