  1. This worked perfectly! If you use remote desktop to do this, press Alt-F4 to reboot the server. Now is there a way to purchase a key for the Evaluation version or must you install the full OS?

    1. Actually, you already have 360 days as a trial period , at the first windows installation you got 180 days , after the first trial period has expired (180 days) , you would use this command to extend the trial period for only one additional 180 days , after that you will need to purchase a key for windows or build a new VM .
