How to Reset Password on Windows Server

What happens when you need to change the admin password because you have lost the old password?

If you don’t have the old password, you can’t access the server to change it. Instead, use the command prompt to reset your administrator password. The following steps can be used on Windows version 2008 R2, 2012, 2016, and 2019.

4. Click Command Prompt.
5. Type in the following:

MOVE C:WindowsSystem32Utilman.exe C:WindowsSystem32Utilman2.exe

The command above makes a backup of the utility manager.

This command replaces Utilman with the Command Prompt. That is necessary to reset the password.

7. Reboot the system.
8. Select the Ease of Access icon.
