If Bluetooth has ever crashed your Windows 10 computer and greeted you with the dreaded Blue Screen of Death (BSOD), you’re in luck because Microsoft has now released a fix. Some users started experiencing crashes after installing the January KB5009596 cumulative update.
Now, Microsoft has pushed the optional KB5011543 Preview cumulative update. Seems optional as it will most likely only affect enterprise users.
Solve the problem
Windows 10 versions affected by the vulnerability include Windows 10 21H2, Windows 10 21H1, and Windows 10 20H2.
“After installing update KB5009596 or later, some organizations pairing Windows devices with Bluetooth devices may receive the error “Your device has encountered a problem and needs to restart. “Blue screen and ‘Stop Code: IRQ NOT LESS OR EQUAL’,” Microsoft said.
“Errors logged on the affected device will appear in the System log in Event Viewer and will be logged as ‘Microsoft-Windows-WER-SystemErrorRe Event 1001’ with the text ‘The computer has restarted from bugcheck. Error Checked as: 0x0000000a’.”
According to BleepingComputer, enabling specific CSP policies can affect the Bluetooth A2dp profile on some endpoints, resulting in BSOD.
Microsoft says there are two possible scenarios for the crash:
If a device that was previously paired with an audio device or phone via Bluetooth reboots after installing the update
After installing the update, the device is paired with another machine via bluetooth
The publication also found that those who currently cannot patch their systems but want to fix the problem can modify the Windows registry before installing KB5009596.
These are the instructions:
Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PolicyManager\current\device\Bluetooth\
Add the following registry keys: {0000110a-0000-1000-8000-00805f9b34fb} and {0000110b-0000-1000-8000-00805f9b34fb} to the ServicesAllowedList value
Obviously, taking a backup is crucial before making any changes to the Windows Registry.
