This is going to be short and sweet. If you’re trying to do the “Update and Restart” option on Windows 10, via the command line, it appears that you can run the command “MUSNotification.exe Reboot” and it will trigger the install/reboot. This is useful for forcing the update to, say, Windows 10 22H2 from a previous version. I have not found a single reference online describing this as the solution to this (despite searching desperately for hours), so I’m documenting this in the hopes it’ll help someone else.
