Hi Christian Womack.
Thanks for your reply. I'm sorry that the scenario in the link I gave didn't help you.
We have determined that this may be some missing system files, please refer to the following steps and try to perform a system file check
- Search for Command Prompt in the taskbar, right click on it, and select Run as administrator mode.
- Enter the following commands one by one, please make sure to execute the next command after the previous one is completed. DISM /Online /Cleanup-Image /ScanHealth DISM /Online /Cleanup-Image /CheckHealth DISM /Online /Cleanup-Image /RestoreHealth SFC /Scannow
- After this, see if you can create a new local administrator account using the method in the link.
If it still doesn't work after this, please refer to the following steps to create a new local administrator account via command prompt.
1 Go to the Command Prompt page (Administrator)
2Then type in the following and press Enter
net user username password /add
Note, please change username and password to your desired username and password.
Then continue typing the following command to set the account you just created as an administrator account
net localgroup administrators username /add
After that, try to log in with the username and password of the account you just created.
I hope the above content can help you, if you have any other questions, or the above content does not help you, please continue to contact me, I will provide you with further assistance, thank you for your support and understanding.
