Microsoft admits to blue screen errors following Windows 11 update

In March 2025, Microsoft acknowledged an ongoing problem affecting users of Windows 11 following the installation of recent updates. The updates in question are associated with the Windows 11 version 2H42 release and include KB5053598, KB5053656, and KB5055523, released on March 11, March 27, and April 8 respectively. Users have reported experiencing the infamous Blue Screen of Death, also referred to as a blue screen exception, particularly with the error code 0x18B that indicates a SECURE_KERNEL_ERROR. This issue has been confirmed in a support document publicly shared by the company, asserting its impact across the affected updates. Microsoft has not only confirmed the existence of this critical bug but has also acknowledged the additional shortcomings associated with the April update, which disrupted Windows Hello functionalities for some users, preventing access through facial recognition and eye scanning technologies. While Microsoft is actively working on a proper fix for these problems, it has released a server-side update intended to disable the change initiating the blue screen errors. This action is meant to assist users in navigating around the issue while Microsoft continues to develop a comprehensive solution. Affected users are encouraged to check for updates frequently, as the server-side patch does not appear on the Windows Update page. In an effort to mitigate user inconvenience, experts advise that users should check for updates multiple times and restart their systems, which may facilitate faster access to the upcoming solutions. With upcoming patches planned for release in May, it remains crucial for affected Windows 11 users to stay vigilant about updates in the meantime, as the overarching aim is to restore normal functionality across multiple impacted areas of the operating system.
