[German]Question for the administrators of Windows Server 2019 systems: What are your experiences regarding the January 11, 2022 updates and boot loops. On Domain Controllers, the boot loops are well known, but Microsoft has released out-of-band updates with a fix. But I have now received reports that a Windows Server 2019 running stably so far with update KB5009557 had forced the servers into a boot loop with update KB5010791.

Windows Server Boot Loop
The security updates of January 11, 2022 has caused serious issues. My blog post Microsoft Microsoft Januar 2022 Patchday Revisions (2022/01/14) provides an overview of these issues – details can be found in the posts linked at the end of the article, if applicable.
Specifically on Windows Server, domain controllers were forced into a boot loop (see Windows Server: January 2022 security updates are causing DC boot loop). As of Jan. 17 and Jan. 18, 2022, Microsoft then submitted out-of-band updates to address the issues. For Windows Server 2019, out-of-band update KB5010791 has been available since Jan. 18, 2022 (see Out-of-band Updates for Windows Server 2019 fixes Jan. 2022 Patch day issues (Jan. 18, 2022)).
However, these updates then did not fix all patch day issues that occurred. It's also stupid that some of the updates were not offered via Windows Update – on the other hand, they were installed automatically on Windows machines despite optional classification. In the blog post Status of January 2022 security updates from Microsoft (2022/01/25).
Boot loop due to update KB5010791
Now German blog reader Holger M. emailed me on February 2, 2022, reporting a boot loop due to update KB5010791 on their Windows Server 2019 instances. Holger wrote:
We applied the KB5010791 to all Windows Server 2019 last night. The update KB5009557 [dated 11/1/2022] was running on these servers, except for the DCs, since 17/01 without any problems. Today around 11am the file server went into a boot loop and booted 6 times in a few minutes interval. KB5010791 seems to be faulty again …
So means that the original update KB5009557 from 11/1/2022 ran without problems on Windows Server 2019, unless it was acting as a domain controller. In contrast, the fix update KB5010791 from 1/18/2022 (see Out-of-band Updates for Windows Server 2019 fixes Jan. 2022 Patch day issues (Jan. 18, 2022)) causes a boot loop on this server. Holger mentioned several machines running Windows Server 2019 and sent me the following excerpt from the error message:

Further confirmations
In the meantime I have received further confirmations to my post in a German Facebook admin group. Jan S. writes:
We experienced this error with a VM. Complete restore from backup helped …
And Patrick K. also made corresponding observations:
Bootloop… Had this yesterday in a terminal farm..the whole thing has then built up to the point that 2 of the servers had to be reinstalled.
Anyone of you with similar experiences?
