During the initial profile account creation, Windows 10 will fail causing it to create a 'DefaultUser0' account which requires a password that; is not supplied, and unable to be reset.
To fix the issue without having to restore the computer, create a new user using the Administrator account in 'Safe Mode with Command Prompt':
- From the user sign in screen, while holding SHIFT, click the power button in the lower right, and click reset.
- This will bring you to the Windows 10 boot options
- Select Troubleshoot > Advanced Options > Startup Settings > Restart
- After restart, select '6)Enable Safe Mode with Command Prompt'
- If prompted, select the 'Administrator' account
- Create a new user account: net user <username> <user password> /add
- Exit, and restart the computer. You should now be prompted to create a new user through the Windows 10 creation process, or you will be prompted to log in as your newly created user.
After logging in as your newly created user, you can manually remove the 'DefaultUser0' account using the following method.
- Delete the 'DefaultUser0' folder from C:\Users\
- Delete the 'DefaultUser0' registry entry from: HKLM\Software\Microsoft\Windows NT\CurrentVersion\ProfileList\
- Click on each of the listed profiles and check the 'ProfielImagePath' entry to verify the associated profile
