Windows 11 update causing BSODs and Wi-Fi issues, Microsoft confirms

Microsoft has confirmed two separate bugs in Windows 11 that affect some users, reports Windows Latest.

The most serious issue can cause a so-called Black Screen of Death (BSOD) with the error code KERNEL_SECURITY_CHECK_FAILURE. The bug has been linked to certain graphics card configurations and a bug in the system file dxgmms2.sys, which manages DirectX memory.

At the same time, a bug in the optional January update (KB5074105) is causing problems with Wi-Fi. Some PCs apparently can’t connect to Wi-Fi networks that use the WPA3-Personal security protocol.

According to Microsoft, both of these issues have been fixed in Windows 11 Build 26200.7840 (KB5077181) and later versions, which was released earlier this month and is now being rolled out to users in stages.
