KB5029351 was released this week and the update package brought with it some interesting features. For example, there is a new hover behavior when you click on the search box; when you hover over it, a search flyout box might appear.

Plus, KB5029351 also brought the enable optional updates feature, which will effectively allow administrators to configure the monthly, optional cumulative updates for commercial Windows 11 devices.

But, as with any other update package, KB5029351 also comes with one big issue: a known issue that displays the UNSUPPORTED_PROCESSOR error. This known issue was reported a day after the package was released, and Microsoft already acknowledged it.

Windows 11, version 22H2; Windows 10, version 22H2; Windows 11, version 21H2 are all affected by this issue.

Microsoft has received reports of an issue in which users are receiving an “UNSUPPORTED_PROCESSOR” error message on a blue screen after installing updates released on August 22, 2023 ( KB5029351) and then restarting their device. KB5029351 might automatically uninstall to allow Windows to start up as expected.
