1. Create a Windows 10 installation tool Make sure that you have a blank flash drive that is at least 8 gigabytes in size, then do the following:
- Attach the flash drive to your computer.
- Open the Windows 10 download page.
- Click Download tool now
- Double-click the downloaded tool.
- Follow the on-screen prompts, making sure to use your flash drive as the installation location.
- Leave the flash drive plugged in after the creation process completes.
2. Change your computer's boot order. This is necessary in order to prompt your computer to start from the flash drive rather than the hard drive.
- Access your computer's BIOS.
- Select your flash drive's name, then press + (or the "Up" key listed in the legend on the right side or bottom of the screen) until the flash drive is at the top of the list.
- Save and exit using the key(s) listed in the legend on the right or bottom of the screen.
3. Open Command Prompt. On the setup screen, press Shift+F10. You should see the Command Prompt window open.
4. Replace Utility Manager with Command Prompt. Utility Manager is a service which has an icon available on the lock screen. By replacing Utility Manager with Command Prompt, you'll be able to execute administrator-level functions without having to log in
c:\windows\system32\utilman.exe.bak into Command Prompt.
- Press Enter
copy c:\windows\system32\cmd.exe c:\windows\system32\utilman.exe into Command Prompt.
- Press Enter
5. Restart your computer. Type wpeutil reboot into Command Prompt, then press â†µ Enter. At this point, you'll need to remove your installation media from the computer in order to ensure that Windows reboots to the login screen rather than back into the installation setup.
If Windows boots into the installation setup before you have a chance to remove the installation flash drive, remove the flash drive and then press (or press and hold) your computer's hardware Power button.
6. Open Command Prompt Once the lock screen loads, click the "Utility Manager" icon, which resembles a dial with a right-facing arrow in the middle, in the bottom-right corner of the screen. A Command Prompt window will open.
- If you don't replace Utility Manager with Command Prompt, clicking this icon will open the Utility Manager instead.
7. Create a new user. Once Command Prompt opens, do the following:
- Type in
net user name /add
- making sure to replace "name" with a username of your choice. Press Enter. Type in
net localgroup administrators name /add
- again replacing "name" with the name of the user you just created. Press Enter
