Microsoft is blocking Windows 11 22H2 on some Intel PCs due to BSOD

Windows 11 version 22H2 is rolling out in phases, and if you ignore the performance issues experienced on Nvidia hardware, it seems to be pretty stable for most users. However, a new issue has surfaced that could cause affected machines to crash with a Blue Screen of Death error.

This issue is caused by the Intel SST audio driver and Microsoft has confirmed that affected users will not be allowed to install version 22H2. It also includes those systems running Windows 10, as Microsoft has blocked all affected hardware configurations from being upgraded regardless of operating system version.

As we noted earlier today, Microsoft acknowledged the Intel compatibility issue in a September 22 support document update. The documentation states that driver IntcAudioBus.sys with a file version earlier than 10.29.0.5152 or 10.30.0.5152 can cause problems.

You can verify that you have the Intel SST Audio Controller by navigating to Device Manager (search in Windows Search). In Windows Device Manager, look for the hardware named "Intel® Smart Sound Technology (Intel® SST) Audio Controller."

For those who don’t know, Intel SST is a signal processor that handles playing music and voice commands. This feature is available on Core and Atom processors.

We don’t know if Microsoft is willing to make any changes to Windows 11 to mitigate the issue, but it looks like the best fix is ​​to update the drivers to a newer version. Updated drivers depend on your PC manufacturer, so you can check for updates on the OEM website or Windows Update > Optional Updates.

When you upgrade to a version higher than 10.29.0.5152 or 10.30.0.5152, the compatibility restriction for Windows 11 22H2 should be lifted.

Microsoft also acknowledged another known issue that only affects enterprise customers.

Microsoft says a bug in Windows 11 may prevent Group Policy preferences from working as expected. When enterprises use this feature, file copying may fail or create empty shortcuts.

Large cumulative update to fix bugs in 22H2

Microsoft has started working on a large cumulative update to address several known issues in the operating system.

For example, Windows 11 22H2 Build 22621.607 fixes an issue where some users are unable to install apps that are not signed by the Microsoft Store. A bug that caused Microsoft Store updates to fail has also been resolved. Likewise, Microsoft also fixed an indexing issue with Windows Search that caused the service to perform slower than usual.

Microsoft fixed an issue affecting Task Manager where applications stopped working when you switched between light and dark modes.

Microsoft is currently testing Windows 11 Build 22621.607 with users in the Release Preview channel, and it will be released to the public in days or weeks.
