Updates for Windows 11 21H1 – 22H2
A list of Windows 11 updates can be found on this Microsoft web site. I have pulled out the details below. Microsoft now provides the following updates for the Windows 11 versions mentioned above.
Update KB5022303 for Windows 11 22H2
Cumulative Update KB5022845 raises the OS build for Windows 11 to 22621.1265 and includes quality improvements as well as security patches, but no new operating system features.

This update is automatically downloaded and installed by Windows Update, but is also available from the Microsoft Update Catalog and via WSUS as well as WUfB. The patch includes the Windows 11 Servicing Stack Update, which raises its build to 22621.1190. The update causes various problems, which are listed in the support article.
Update KB5022836 for Windows 11 21H2
Cumulative Update KB5022836 raises the OS build on Windows 11 to 22000.1574 and includes quality improvements as well as security patches, but no new operating system features. Regarding the implemented improvements, Microsoft mentions the following:
- This update addresses security issues for your Windows operating system.
- This update makes miscellaneous security improvements to internal OS functionality. No additional issues were documented for this release.
Microsoft is keeping quiet about the details of the other fixes. These were already documented with the January 2023 preview update, see Windows 11 21H2: Preview-Update KB5019274 (Jan. 19, 2023). Microsoft notes that this update makes quality improvements to the servicing stack (is responsible for Microsoft updates).

Windows Server 2022
For Windows Server 2022, according to this Microsoft site, cumulative update KB5022842 (Windows Server 2022) has been released, raising the OS build to 20348.1547. Among the fixes this update makes, Microsoft writes:
- New! It updates the text and web link for Windows Admin Center (WAC) notifications. These appear after you sign in to the desktop unless you have turned them off. The WAC notifications highlight the available Windows Server management options.
- This update addresses an issue that affects searchindexer.exe. It randomly stops you from signing in or signing out.
- This update addresses an issue that affects local Kerberos authentication. It fails if the local Key Distribution Center (KDC) service is not active.
- This update addresses an issue that affects cbs.log. This issue logs messages that are not error messages in cbs.log.
- This update addresses an issue that affects a virtual machine (VM) that has a dual stack IPv4 and IPv6 private IP (PIP) address. When you migrate the VM from one host to another, the PIPv6 address stays mapped to the old host's IPv6 Physical Address (PA). Because of this, the IPv6 PIP stops working.
- This update addresses an issue that affects the Domain Name System (DNS) suffix search list. When you configure it, the parent domain might be missing.
- This update addresses an issue that affects all commands that change security tags. On Windows 11, version 22H2 computers, the change will fail if you update the Network Controller but not the Remote Server Administration Tools (RSAT) clients.
- This update addresses an issue that might occur when the Input Method Editor (IME) is active. Applications might stop responding when you use the mouse and keyboard at the same time.
- This update addresses an issue that might affect FindWindow() or FindWindowEx(). They might return the wrong window handle.
- This update addresses an issue that affects AppV. It stops file names from having the correct letter case (uppercase or lowercase).
- This update addresses an issue that affects Microsoft Edge. The issue removes conflicting policies for Microsoft Edge. This occurs when you set the MDMWinsOverGPFlag in a Microsoft Intune tenant and Intune detects a policy conflict.
- This update addresses an issue that affects Active Directory Federation Service (AD FS). The issue fails to apply the RequirePDC flag setting of "false."
- This update addresses an issue that affects MSInfo.exe. It does not correctly report the enforcement status of the Windows Defender Application Control (WDAC) user mode policy.
- This update addresses an issue that affects the Resilient File System (ReFS) MSba tag. The issue causes a nonpaged pool leak.
- This update addresses an issue that affects the Resilient File System (ReFS). The issue causes high nonpaged pool usage, which depletes system memory.
- This update addresses an issue that affects parity virtual disks. Using Server Manager to create them fails.
Microsoft notes that this update makes quality improvements to the servicing stack (which is responsible for Microsoft updates). This update is automatically downloaded and installed by Windows Update, but is also available from the Microsoft Update Catalog and via WSUS and WUfB. Microsoft lists a known issue with WSUS in connection with the update.
Addendum: I got several reports from German blog readers, saying, that their virtual machines can't boot either due to a "security violation" or due to a missing boot manager. Deactivating "Secure boot" should solve the issue.
