Azure VM no response after installing update and auto-restart

When there was an update being installed and it required a restart, Azure VM restarted during off-hours, then it went into no response state. I had to stop and start it via portal.

It occurred a couple of times already. One example is KB4592440.

=====

Windows Setup log:

9/12/2020 11:29:15 AM A reboot is necessary before package KB4592440 can be changed to the Installed state.

System logs:

10/12/2020 1:18:00 AM The process C:\windows\system32\svchost.exe (MyVM) has initiated the restart of computer MyVM on behalf of user NT AUTHORITY\SYSTEM for the following reason: Operating System: Service pack (Planned) Reason Code: 0x80020010 Shutdown Type: restart Comment:

Other system logs:

The Windows Modules Installer service entered the running state.

The Update Orchestrator Service service entered the stopped state.

The Update Orchestrator Service service terminated with the following error: This operation returned because the timeout period expired.

...(many other service went into stopped state)...

The Windows Event Log service entered the stopped state.

The Remote Desktop Services service entered the stopped state.

===========

No more logs. MyVM is stuck in nowhere, until I stopped & started it. Then there was a Setup log:

Package KB4592440 was successfully changed to the Installed state.

Appreciate any help.
