This article is about how KB4568831 causes ThinkPad notebooks to crash and what to do with the blue screen. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

According to Windowslatest, the latest batch of cumulative updates to Windows 10 has brought a series of new problems to users, including dead blue screens, performance issues and another Bug that caused problems with the start menu. It was in the supporting documents quietly released over the weekend that Microsoft admitted that KB4568831 and subsequent cumulative updates had caused system crashes and blue screen problems in some Lenovo ThinkPad notebooks. Key errors include "SYSTEM_THREAD_EXCEPTION_NOT_HANDLED" crash, 0xc0000005 access denied, and system crash of process ldiagio.sys.

In a separate support document, Lenovo acknowledges these reports and highlights errors that users may encounter after installing the latest cumulative update to Windows 10, including:

1. A blue screen appears when turning on the computer, opening Lenovo Vantage, and running a Microsoft Defender scan.

2. Windows Hello failure

3. Intel supervisor engine and infrared camera failure in device manager

The problem seems to be caused by cumulative updates to Windows 10, compatibility issues between UEFI settings and Lenovo's Vantage application. In the cumulative update, Microsoft made adjustments to access PCI devices and functions in UEFI, resulting in problems such as crashes and blue screens.

Lenovo and Microsoft have confirmed that the affected models include the 2019 and 2020 ThinkPad models. Although blue screens are a very serious problem, the good news is that Lenovo and Microsoft have provided a relatively simple temporary fix.

If your ThinkPad device has a blue screen problem, you can solve this problem by disabling the Enhanced Windows Biometric Security setting in UEFI. If you cannot disable this setting, you should uninstall the update released in September or August and suspend the Windows update until Microsoft releases the fix.
