I created this script to help me log out from multiple systems after a password change.
Although the initial script that depended only on the qusercommand worked there was one computer identified by IT that still kept an RDP session active.
I was suggested to use qwinstawhich seems that it did the trick. I am not sure what the real difference between the two.

Since the returned session id is the same, I updated the gist to use both commands before feeding the qwinsta.
