This command will determine where your server drive is. You will need this drive later, to reset the password of your Windows.

Note: as we have started with bootable media, so system reserved partition will be used. No hard disk has been changed. Only the drive path has been changed temporarily, which can be changed back by restart the Windows Server again.

Here you will need to use the command one by one:


Note: here X: is an exemplary drive, you will need to replace it with your server driver path.

CD windows\system32
ren utilman.exe utilman.exe.bak
ren cmd.exe utilman.exe

CMD to Ease to access
CMD to Ease to access

the above commands will restart your system. Again you will be placed in CMD, there you will find an Ease to access button at the bottom, click on it. There you will find the Utliman.exe file, you will need to access it and change details by using these commands:

net user administrator Admin123
net user administrator /active:yes

The operation above has changed the Utilman.exe to Utilman.exe.bak and CMD.exe to CMD.bak. the second section of commands has created a new user with no password. Now remove your USB and restart your system. login the user and use Windows Server 2012 R2.

Revert changes

To revert the change back to normal, you will need to apply the same procedure given above. Which is basically changing the Utilman.exe.bak to Utilman.exe. you will need to go to Windows setup > Repair your computer > Troubleshoot > Command Prompt then use the commands below again:

CD windows\system32
E:\Windows\System32>del Utilman.exe
E:\Windows\System32>copy Utilman.bak Utilman.exe
         1 file(s) copied
