Windows 10: No administrator account in a PC, how to get one?

By mistake, my account type on the PC was changed to non administrator account. Now both accounts in the PC are non administrator accounts. Is there anyway to change it back?

Settings can't be opened using the built-in administrator account


Hello,
Unfortunately I have the same issue as Dabz from upgrading win7 to win10.
I've tried opening settings using all the suggested methods and it will not load using my account with Administrator access nor the built-in Administrator profile. I also tried other methods not listed such as using Run. Control panel is just a stepping stone to add users in Settings.
I'm also having explorer.exe issues, which I believe is preventing Settings from loading.
Using cmd (Admin) I successfully created a new user profile [and granted admin access also using cmd (Admin)], however win10 will not allow this account to log on. win10 does not list this new user within control panel but it does in the start menu. win10 will not allow to log in or switch to the new account via the start menu either.
I can access settings in Safe Mode but this will not allow me to create a new account.
Any help/suggestions will be greatly appreciated.
Cheers

 

Weird account name and lost Administrator rights.


Well, I know what I would do.

Under Settings, Accounts, Family & other users, then under Other users, add someone else to this PC. Then click the link for "the person I want to add doesn't have an email address". Then click the link for "Add a user without a Microsoft account". Then enter a temporary user name like TempAdmin. When the account appears in the Other Users list, click on it. Click change account type. Make the temporary account an Administrator.

Log in as the temporary administrator account, and copy all the files you want to keep from both the Andrius folders under Users to the temporary account's folder. Then delete whatever Andrius users are listed under settings, accounts. Go back to the Users folders and delete any remaining Andrius folders in there. Reboot the computer, log in as the temporary administrator and recreate an Andrius account using the exact same steps you made the temporary account - you can convert it to a Microsoft account if you want later.

Then do the rest of the steps to copy all your files back and delete the temporary administrator account.

 

Can't Access Administrator Account - Windows 10

Hi,

To resolve this issue, we suggest that you start your PC in safe mode. Safe mode starts Windows in a basic state, using a limited set of files and drivers. For steps on how to start your PC in safe mode, refer to the following link:

Start your PC in safe mode in Windows 10.

Once you are in safe mode, let's enable the built-in Administrator account on your PC. Follow the steps below:

• Right-click on the Start menu.
• Click on Command Prompt (Admin).
• Type net user administrator /active:yes on the command prompt, and press Enter. This command will enable the built-in Administrator account.
• Type net user administrator password on the command prompt, and press Enter. This will change the Administrator account's password to
  password.
  
• Reboot your computer, and sign in as Administrator.

Once you are signed in as Administrator, let's make your old account as Administrator. Follow the steps below:

• Right-click on the Start menu.
• Click on Settings > Accounts > Other Users.
• Click on your other account and click on Change account type.
• Under Account type, select Administrator.
