[German]Currently, there are a lot of reports from users about issues that occur in connection with update KB4549951 on Windows 10 version 1903 or version 1909. Here is a short overview.
Update KB4549951 for Windows 10 Version 190x
Cumulative Update KB4549951 was already released on April 14, 2020 and raises the OS build to 18362.778 (Windows 10 V1903) and 18363.778 (Windows 10 V1909). The update is available for Windows 10 version 1903, for Windows 10 version 1909, and for Windows Server version 1903 and Windows Server version 1909.
The cumulative update includes quality improvements but does not include new operating system features. In the blog post Patchday: Windows 10 Updates (April 14, 2020) I have listed the list of improvements and fixes. Microsoft states that there are no known issues related to the update.
Addendum: Since a few days the support article KB4549951 has been extended by the following.
We have seen social media reports related to KB4549951 that mention Bluetooth, a stop error with a blue screen, and other related issues.
Microsoft writes that in the social media one has read reports about BlueScreens, Bluetooth problems or other errors. Redmond also writes that ‘to this day’ these problems have not been seen in telemetry, support data or customer feedback channels. The messages are being investigated and closely monitored, but nothing can be confirmed at this time.
Reports about issues with update KB4549951
I had already briefly mentioned in the blog post April 2020 Patchday: Review and issues that some people run into installation errors, or that a temporary user profile is used after an update installation. There is also a note about possible printer problems in connection with update KB4549951.
In the German comments to the blog post April 2020 Patchday-Nachlese there are some BlueScreens mentioned in connection with the update. However, they seem to appear only sporadically and were gone after several restarts. If you search the Microsoft Answers forum for update KB4549951 issues, there are a number of hits.
Bleeping Computer has picked up a few isolated hits in this article. In particular, installation errors (I already mentioned within my old blog post April 2020 Patchday: Review and issues) seem to plague a number of users. BlueScreens were also reported, but they were gone after the automatic uninstallation of the update. Bleeping Computer’s article still lists some additional issues like non-booting systems or freezing systems during streaming. However, I have not seen a accumulation of any particular error pattern indicating a problem with the update package.
There are lots and lots (and lots!) of reports of problems with this month’s Win10 v 1903/1909 cumulative update, KB 4549951. Other than the recurring race condition/temporary profile bug, which has been around for months, I don’t see any patterns. Do you? https://t.co/9nBIeGrAbv

Woody Leonhard has also taken up the matter in a ComputerWorld article and refers to this article in the above tweet. Also there it becomes clear that there is no certain pattern of errors. Hence my question: Is anyone affected by problems in connection with update KB4549951?
