} So if you just type:
that will get Microsoft Updates on your local server.
If you want to get Microsoft Updates from remote server, then type like:
Get-MicrosoftUpdate -ComputerName "MyHyperVHost01" |
Get-MicrosoftUpdate -ComputerName "MyHyperVHost01" That will give you Reboot requirements as well.
