The main difference between your administrator account and the built-in administrator account is that the built-in administrator account has full unrestricted access to your computer. So, enabling the built-in administrator account can be helpful when you are having privileges problem on Windows 10.


These are the steps for enabling the built-in administrator account.

  1. Hold Windows Key and press (release Windows Key). Click Command Prompt (Admin)
  2. Type net user administrator /active:yes and press Enter. You should see a message Command run successfully.

It’s always good to password protect your administrator accounts to prevent people from making changes in the PC.

  1. Type net user administrator <Password> and press Enter (you should write the password which you want to set for the administrator account in place of <Password>)


  1. Type net user administrator * and press Enter. You will be asked twice to enter the password that you want to set for the administrator account. Just type your password and press Enter

Now try to run the program and there shouldn’t be a problem. If you want to disable the administrator account then follow the below step
