Settings cant be opened using the Built-in Administrator account

When we received the acer we open a new outlook.com account. Never used it for any thing else. We apparently used the wrong password to many times and MS locked us out of the acct. They will not let us back in. We have the password to log into the computer and I used another outlook account and made that an administrator acct. Now when I go and try to use different app I get the message below. The outlook acct that was open with the unit is NO LONGER ANY GOOD.

PS: WIN 10,


Messge that come up when opining app--
This app can't open
Settings cant be opened using the Built-in Administrator account Sign in with a different acct
and try again

Press Windows key + R to open a run dialog box. Type netplwiz and enter. Click the add button. A blue window will open. At the bottom is a link: Sign in without a Microsoft account (not recommended). Click on that. On the next window click local account. Fill in the info for a local account click finish.

The new account should appear in the list of accounts in the first netplwiz window. Click on the new account and then the properties button. Click on the group membership tab. Check the circle for Administrator and OK. The new account should now be listed in the first window as belonging to the Administrators group. Click OK.

Now restart the computer and log into that new account you created. Then you can fix the other user accounts on the computer.
