Windows 11 KB5011563 update fixes SMB, DirectX blue screens

Microsoft has released the optional cumulative update preview KB5011563 for Windows 11, which includes fixes for stop errors that cause blue screens of death (BSOD) and other issues.

This preview update is part of Microsoft’s planned March 2022 monthly “C” updates, allowing Windows 11 users to test the upcoming fixes released on April 12 as part of next month’s Patch Tuesday.

Unlike regular Patch Tuesday Windows updates, the scheduled “C” non-security preview releases are optional. They are only used to test bug fixes and performance improvements prior to the general release, so they do not provide security updates.

To install the KB5011563 update, you need to go to Settings > Windows Update and manually ‘Check for updates’. Since it’s an optional update, Windows won’t install it until you click the “Download Now” button.

You can also manually download and install this month’s Windows 11 cumulative update sample from the Microsoft Update Catalog.

Solutions for blue screen and more

As mentioned at the outset, the highlights of today’s Windows 11 Optional Update are fixes for two BSODs triggered by stop errors in DirectX and the SMB server.

As explained by Microsoft, KB5011563 “resolves a stop error (0xD1, DRIVER_IRQL_NOT_LESS_OR_EQUAL) in the DirectX kernel component” and another problem “that causes stop error 0x1E in the SMB server (srv2.sys).”

The update also adds support for simultaneously displaying up to three high-priority toast notifications, a feature designed specifically for apps that send notifications for calls, reminders, or alarms using Windows notifications.

It also fixes an issue that could cause Microsoft OneDrive files to lose focus after being renamed and pressing the Enter key.

After the implementation of KB5011563, Windows 11 will return the corresponding settings page when searching for the word ‘widgets’.

What’s New in Windows 11 KB5011563 Update

After installing today’s non-security cumulative update preview, the Windows 11 build number will be changed to 22000.593.

The Windows 11 cumulative update preview KB5011563 contains 26 quality improvements and fixes, including:

Fixes an issue that could cause SystemSettings.exe to stop working.

Fixes an issue that increases the Windows startup time. This issue occurs because a UI thread in a network API stops responding when a 5G wireless wide area network (WWAN) device activates slowly.

Addresses issue that may cause Kerberos.dll to stop working within the Local Security Authority Subsystem Service (LSASS). This occurs when LSASS processes concurrent Service for User (S4U) user-to-user (U2U) requests for the same client user.
