Update to BIOS causes Windows 11 activation failure.
Update to BIOS causes Windows 11 activation failure.
faced difficulties with Ethernet on my Z690 M. Aorus Elite DDR4 board. Consulted Gigabyte, they advised a BIOS upgrade. Updated from F6a to F7a, but the issue persisted. It turned out a Microsoft BIOS update is a hardware modification. Now Windows 11 Pro isn't activated, and troubleshooting fails because I already performed the changes when installing the board. A Microsoft support representative helped, suggesting checking with the motherboard vendor about BIOS compatibility with Windows 11. Should I really purchase a new product key for a BIOS update?
The BIOS update doesn’t affect the motherboard brand, model, or serial number. The problem likely lies elsewhere. Did you run sfc /scannow to verify Windows for issues?
I'm not sure why the BIOS update impacted activation. I assumed CSM or Secure Boot could be involved, but they were configured identically on both versions. I didn't run an SFC scan. Instead, I used the Windows 10 product key I originally had, not the updated one. It resolved the issue immediately. The Windows support team didn't advise trying a different key. Appreciate the help!
