Reset your Windows password in 5 minutes

12 april 2023 Solutions

Every once in a while you run into a server that is not in a domain and nobody knows the Administrator password. What do you do?

When you boot the server with a standard Windows ISO file you go into the recovery options and open a Command window. In that window, browse to the server’s system drive (\Windows\System32) and copy utilman.exe to utilman.org.

Now copy cmd.exe to utilman.exe and check if this was successful.

When you continue the boot process click on the Accessibility Options on the login screen. If everything went according to plan a Command window should open.

In this window you can change the Administrator password:

net user Administrator <newpassword>

Now repeat the boot procedure with the ISO file to revert the changes. So copy utilman.org to utilman.exe and delete utilman.org. Finally, disconnect the ISO file.
