Windows 10: Lost administration rights on admin account

I found another thread on the same topic, but it was "locked" - so here is another one:


After recent update and several uninstall and installation procedures my account was not able to sign in to windows. While signing in with another user account and trying to use command prompt as an administrator, the administration account seems to have lost administration rights.


When trying to sign in windows states that sign in method is not allowed!?


Urgent help needed -

Lost administrative rights & Account

Hi,

If you have another admin account you can log into that account and change the permission of the other account. If this is the only account your PC then follow the steps to change account permission to admin.

• Press Windows key + R and type netplwiz and hit Enter.
• Select the account and click on Properties.
• Under Group membership tab select Administrator and click on Apply and OK.

Hope this helps. Thank you.

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.
