Key notes
- It appears that KB5011543 didn't just bring the Search Highlights feature to Windows 10.
- Besides that, it also fixed a critical Bluetooth bug that was causing problems since January.
- Microsoft also provided an official workaround to this problem on the official release page.
The Redmond-based tech giant has just released an important fix for a critical Bluetooth bug that was causing blue screens of death on Windows 10.
This is apparently a thing since the January KB5009596 builds. The fix was issued via the latest Windows 10 builds 19042.1620, 19043.1620, and 19044.1620, under KB5011543, that were released earlier today.
Let’s get right into it and see what exactly we are dealing with, or were dealing with, since Microsoft has finally fixed this horrendous glitch.
BSOD Bluetooth error finally fixed with KB5009596
After installing KB5009596 or later updates, some organizations which have Windows devices paired to Bluetooth gadgets might receive this error: Your device ran into a problem and needs to restart.
Of course, this dreaded error message was accompanied by a blue screen and Stop code: IRQ NOT LESS OR EQUAL.
The error logged on affected devices will be in the System log in Event Viewer and will be logged as Microsoft-Windows-WER-SystemErrorRe event 1001 with the text The computer has rebooted from a bugcheck. The bugcheck was: 0x0000000a .

Now we can breathe a sigh of relief as KB5011543, the same one that brought Search Highlights to Windows 10, finally fixed the issue.
