This article is for sysadmins who know better, wanting to Shut down or Restart (or even enter Sleep) over RDP anyway.

At left, user clicked on Start, Power, then has three choices. Using RDP at right, choices are rather limited.

Using Command Prompt

Open a Command Prompt

a. To initiate a Shut down, type:

shutdown /s /t 0

then press Enter

OR

b. To initiate a Restart, type:

shutdown /r /t 0

then press Enter

Because of the 0 second delay you specified, you’ll want to be very sure you really intend to do this immediately, before you press that Enter key!

Note: these techniques also work with Microsoft

• Windows Server 2008/2008 R2
• Windows Server 2012/2012 R2
• Windows Server 2016
