When I need to manually update Microsoft 365 Office Applications, I usually open an Office app, then go to File > Office Account > Update Options > Update Now.

It works but the problem is that sometimes I need to update them on a computer that I don’t have a subscription account to work with. Besides, it’s quite tedious too.

A command line would be much nicer, like this.

"C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe" /update user

Or, if you want to run the update in total silent mode,

"C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe" /update user displaylevel=false forceappshutdown=true

What’s nice about it is that you now can add the command line to your login script or be part of your new installation routine.
