This one is super cool and you will amaze your boss. Many times, I’m asked if I can find who is logged into a machine.

As long as you have PSRemoting enabled across your network you can run this:

get-wmiobject win32_computersystem -computer IP or name | select username

or you can do a | select * and it will give you more info.
