Watch out for new issues in Windows 11 KB5014019 update

A third-party antivirus from Trend Micro is reportedly unable to fully complete virus scans, apparently due to some sort of bug in Windows 11 KB5014019. The exact reason is still unclear, but Trend Micro says the problem is related to User Mode Hooking (UMH), a feature used in its antivirus protection tool.

KB5014019 is an optional update and does not include security features. For uninitiated optional updates, which Microsoft designates as C updates, they are generally released during the third or fourth week of each month.

Optional updates are clearly labeled “preview” in Windows Update and are used to test fixes, improvements, and even new non-security features. In this case, KB5014019 comes with a couple of new features, including support for Windows Spotlight on the desktop, a feature that was originally supposed to debut with version 22H2.

Microsoft previously warned that optional updates should not be deployed to all client systems. Rather, the optional updates give users a chance to try out the non-security fixes the company plans to roll out with Patch Tuesday next month.

Issues in KB5014019 for Windows 11

As mentioned at the beginning, Trend Micro claims to be aware of an issue where updating may break features such as the Ransomware Protection feature.

A bug in KB5014019 affects the UMH component used by several Trend Micro products for server and endpoint security. It is also used for advanced ransomware protection, but the driver will stop working after deploying the optional preview update.

“[Users who apply the patch] and rebooting would find that the Trend Micro UMH driver would stop,” the company said.

The company is working on a fix to fix the bug that causes ransomware protection and other features to crash, and a fix will be released before the June 2022 Patch Tuesday update.

Installation problems with the latest Windows 11 optional update

On Reddit and Feedback Hub, users reported another issue where the optional update fails to install with vague error messages.

“For several days after receiving the message “Cumulative Update 2022-05 for Windows 11 for x64-based Systems (KB5014019) is available” I said OK but the system always responded “This update failed to install, but you can try again ( 0x800f081f)”. The KB5013943 update was recently added with the same result. I repeated the procedure several times a day”, noted one of the interested users.

Additionally, it appears that a bug affecting .NET Framework applications has not been fully fixed in the patch and may break the functionality of some applications such as SteelSeries GG.
