This week's Windows optional cumulative update previews have introduced a compatibility issue with some of Trend Micro's security products that breaks some of their capabilities, including the ransomware protection feature.
"The UMH component used by several Trend Micro endpoint and server protection products is responsible for some advanced features such as ransomware protection," the antivirus vendor revealed.
"Trend Micro is aware of an potential issue where customers who apply the optional Microsoft Windows 11 or Windows 2022 optional preview patches and reboot would then find that the Trend Micro UMH driver would stop."
Windows users have to manually check for them from Settings > Windows Update.
Impacted Windows platforms include both client and server versions with the problems experienced on systems running Windows 11, Windows 10 version 1809, and Windows Server 2022.
Trend Micro customers who have installed the optional Windows optional patch may either uninstall the patch temporarily or reach out to support to get a UMH debug module that should revive their security solution's capabilities.
