Reset Windows Server 2016 password with installation disc
If you have the original Windows installation disc, you can reset your forgotten Windows Server 2016 password by following these steps:
Start the server from the Windows Server 2016 installation DVD. When the Setup screen appears, press SHIFT + F10 to open a command prompt.
At the command line, run the following commands:
ren Utilman.exe Utilman.exe.original
copy cmd.exe Utilman.exe
shutdown -r -t 0
The server should now restart and present the login screen. Press Windows Key + U or click Ease of Access button , command prompt will appear and type:
