According to aggrieved users, the problem affects Windows 10/11 installations that were legally activated using Windows 7/8 product keys as part of a free upgrade offer from Microsoft. However, following last month’s update some of those installations are reportedly getting deactivated if any hardware component in the PC is changed or the BIOS is updated.
The issue has been confirmed by The Verge’s senior editor Tom Warren, who says one of his test PCs also got deactivated after swapping out a motherboard, requiring him to buy a new Windows 11 license to keep using the device. At least one Windows user also filed a complaint with the FTC after his Windows 10 installation was deactivated after a hardware change.
