In testing the August 2024 security update for Windows Server 2019 (KB5041578) we are finding the update causes some Windows Server 2019 servers to become unresponsive. 

There is also a thread on Reddit of many admins experiencing this same behavior. 

A workaround has been to stop the “Cryptographic Services” service, purge the contents of C:windowssystem32catroot2 

Reboot, then install KB5041578 and the issue does not occur. 

Performing these steps on a “broken” server that was patched before performing these steps also fixes the issue, however you can’t log on to the VM when this is occurring due to the performance issue, it must be done remotely.
