How to determine RDP version used in the remote session on the server?

Hi!

I need to determine the version of RDP used by connected client in the terminal session on Windows Server 2012 R2.

For Windows Server 2008 I found this solution:

But there is no RDS Manager where I can see session Status in Windows Server 2012 R2. How can I determine RDP version? With PowerShell maybe or something else?
