Microsoft: Update previews can abort the boot process with an error message

Microsoft is investigating reports that after installing the recently released Windows update previews, the boot process may fail with an “UNSUPPORTED_PROCESSOR” error message. The update may then uninstall itself automatically to bring Windows into a bootable state.

The update preview fixes some bugs that affect system security. The package provides protection against the downfall Intel CPU vulnerability and corrects problems in the context of hard disk encryption with Bitlocker.

Microsoft: Received some reports

In the Windows Release Health Notes, the developers write that they have received multiple reports that users have seen a blue screen with the error message “UNSUPPORTED_PROCESSOR” at startup after installing the late August update previews.

So that Windows starts as expected, the update can be automatically uninstalled again. On the one hand, this is good news, since the computer remains usable. On the other hand, there are no protective measures that users assume are now active. If anyone encounters this problem, Microsoft’s developers ask for a report through the integrated feedback hub, which opens when you press the Windows and F keys at the same time.

The developers are currently investigating whether the cause of the error lies with Microsoft. Since Windows 11 no longer officially supports many older processors, but the operating system can still be installed on it with tricks, the idea that a check should prevent such installations is obvious. However, since Windows 10 installations are also affected by the problem, this can actually be ruled out. It is to be hoped that Microsoft will be able to fix the problem by the official patch day in mid-September.
