Not having an administrator password is causing all the usual problems.
On settings I wind up on one account that I use pin..
When I first turn pc on I am already informed that my sign-in/password is wrong but I have not done anything yet. I hit the OK button and 2 accounts are shown. So I have to use the pin to start. The account is named "Other"
Control Panel only shows 1 account and that is the Administrator (needs password) and no place to enter one.
Tried making Microsoft Accounts, enabling hidden administrator, even when I get a security code that will work but then the password does not work.
Going thru all the files and folders I can see, occasionally I will see the computer owner which correct EXCEPT the name is all in capital letters. I named the same name but not all caps. My current name only the 1st letter is in caps
I am the person who did something with playing around in the settings(?) not the registry. As a couple of weeks ago my account was "Local Administrator" now it is "Local password protected"
I'm 70 yrs old and this is causing me to get more gray hairs
