Please do the following:

Temporary Note: Jamie, please confirm that the “Method 4” presented below describes in detail how you solved this password recovery issue.

You need to connect a USB thumb drive so that it can setup a forgotten password reset folder. It then takes you through a forgotten password wizard, which you are required to put in a new password. 

So old password, which is blank, new password which is now password.

Method 4: Use a boot disk to reset your local Windows account password

This method involves accessing system files and administrative commands. You should only attempt this if you have an above-average familiarity with computers.

Step 1: Create Windows 11 installation media

Before proceeding with the reset process, you’ll need a USB drive or a DVD with Windows 11 installation files. If you don't have one, you can create it using another computer.

If you already have the installation media, skip to Step 2. Otherwise, use another computer to download the Windows 11 Media Creation Tool from Microsoft’s official website. Follow the instructions to create a bootable USB or DVD.

Step 2: Boot from the installation media

Insert the installation media into your locked computer and restart it. Enter the BIOS/UEFI settings (usually by pressing a key like F2, F12, DEL, or ESC during startup). Change the boot order to boot from the USB/DVD and save the changes.

Step 3: Access 'Advanced Options'

Once the Windows 11 setup screen appears, follow these steps:

  • Click ‘Next’ on the initial screen.

  • Select ‘Repair your computer’ at the bottom.

  • Go to ‘Troubleshoot’ and then ‘Advanced options’.

Step 4: Open Command Prompt

In the ‘Advanced options’ menu, select ‘Command Prompt’. This will open a command line interface.

Step 5: Replace Utility Manager with Command Prompt

At the command prompt, type the following commands:

  • c: (to change the directory to the C drive)

  • cd windows\system32 (to navigate to the system32 directory)

  • ren utilman.exe utilman.exe.bak (to back up the Utility Manager executable)

  • copy cmd.exe utilman.exe (to replace Utility Manager with Command Prompt)

After executing these commands, close the Command Prompt.

Step 6: Reset your password

Remove the installation media and restart the computer. At the login screen, click the ‘Accessibility' icon at the bottom-right (which now opens Command Prompt).

In the Command Prompt, type: net user replacing with your account name and with your new password. Press Enter.

Step 7: Restore the original Utility Manager

After resetting the password, it’s important to restore the original Utility Manager. Boot from the installation media again, open Command Prompt from the Advanced options, and type:

  • c:

  • cd windows\system32

  • del utilman.exe

  • ren utilman.exe.bak utilman.exe

Close the Command Prompt and restart your computer. You can now log in using your new password.
