Quick hint: Basic computer actions using PowerShell in Windows Server 2012
 | How to manage basic computer tasks in Windows Server 2012, such as logoff, restart and shutdown from the PowerShell?
I do share the same feeling, I really enjoy the new interface but when you are in a RDP session and you want to be fast, there is nothing better than open PowerShell, cmdlet and hit enter and see ya!, right? So here we have a list of common tasks where we can use Powershell and a couple of commands to get stuff done.
Restarting your computer..
Restart-Computer
Logging off your session.. Logoff
Shutdown your computer… Stop-Computer Before doing all that is always good to check the computer name, so the command below will help you out  hostname |
