Windows Server 2012 Installation Disk
First, you will need to download Windows Server 2012 R2 ISO file and burn it on a USB drive. For this purpose, you can use a third-party application like Rufus or continue with the installation and burn it on a USB. We would recommend you to use Rufus, as it is way easier.

Here you will be in Install now, at the bottom left; you will find Repair your computer, click on it.
You will be taken to Choose an Options window, click on Troubleshoot.
Then in Advanced Options, select Command Prompt. Inside the Command Prompt, type the command:
wmic logicaldisk get caption, description,filesystem
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:

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.
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:
