reset windows server password

This procedure is the only one which worked for me on a Windows 2012 R2 RDP session:
Click Start.
Type osk (to bring up the on screen keyboard)
Hit enter.
Once the on screen keyboard is open, hold ctrl+Alt on your physical keyboard, then click on the del key in the on screen keyboard.
Minimize the on screen Keyboard.
