Microsoft has just confirmed that the previously released KB5009596 (March 22, 2022) cumulative update solves the Windows 10 bug that caused BSOD on some devices. The company explained that in some cases, such as when you’re accessing a device connected to your Windows 10 PC via Bluetooth, the issue can cause the problem, and in some cases, a blue screen of death.
Microsoft explained that a previous cumulative update was the culprit for the bug. After installing update KB5009596 or later, some Windows devices may suddenly blue screen after Bluetooth pairing and receive an error saying “Your device has encountered a problem and needs to restart”, Stop Code: IRQ NOT LESS OR EQUAL.
In the system log, Windows logs this as Microsoft-Windows-WER-SystemErrorRe Event 1001 and says The computer has restarted from bug check. Bugcheck: 0x0000000a.
According to Microsoft, the problem occurs when certain Configuration Service Provider (CSP) policies affect the Bluetooth A2dp profile. Microsoft emphasizes that the latest Windows 10 optional cumulative update addresses the issue, and users who have installed the March 22 patch no longer have to worry about anything. We recommend users who do not have the latest patches installed check for updates.
This issue is resolved in KB5011543 and later releases. We recommend that you install the latest security updates for your device. It contains important improvements and issue resolutions, including this one.
