It seems that there’s a critical issue affecting Windows 10 Enterprise LTSC 2019 and Windows 10 IoT Enterprise LTSC 2019 domain controllers.

Microsoft was quick to respond, and it has already released an emergency update for it, so be sure to get it.

The latest update fixes the Local Security Authority Subsystem Service issue on Windows 10 LTSC

As MSPowerUser writes, the emergency update KB5037425 was just released for Windows 10 Enterprise LTSC 2019 and Windows 10 IoT Enterprise LTSC 2019.

The update addresses the bug in the Local Security Authority Subsystem Service (LSASS) that causes high memory usage and system crashes.

It seems that the problem was introduced in a previous update on March 12th, and it affects domain controllers who are in charge of user authentication in the network environment.

The KB5037425 update is available only via the Microsoft Update Catalog, but before you install it, ensure that you have Servicing Stack Update (SSU) KB5005112 installed.

For detailed information, you can visit the KB5037425 documentation page. Seems that a similar issue was present on other versions since Microsoft addressed the Windows Server domain controller issue recently.
