Microsoft has fixed a known Bluetooth issue causing some Windows 10 systems to crash with a blue screen of death after installing the January KB5009596 cumulative update.

The list of affected Windows versions includes only client platforms: Windows 10 21H2, Windows 10 21H1, and Windows 10 20H2. "After installing KB5009596 or later updates, some organizations which have Windows devices paired to Bluetooth devices might receive an error message 'Your device ran into a problem and needs to restart.' with a blue screen and 'Stop code: IRQ NOT LESS OR EQUAL'," Microsoft explains.

During the restart at the end of the update installation process, if the Windows client device was previously paired with mobile phones or other audio devices via Bluetooth.

After updates are installed, at the moment users pair their updated Windows client device with a new mobile phone or audio device via Bluetooth.

IT admins who cannot immediately deploy the KB5011543 cumulative update released on Tuesday can mitigate the issue using Intune or other tools that allow modifying the Windows registry before installing the buggy KB5009596 update.

More information about this known issue and how to mitigate it can be found on the Windows health dashboard.
