WINDOWS 10 Pro 22H2 - accidentally changed admin account to user account

[talkingcats]

Hopefully someone can help or confirm that a reinstall is the only solution

In addition to my user accounts, I created a specialist admin account with elevated rights

I don't know how I did it but I accidentally removed the elevated rights from my administrative account so now it is a user account without privileges.

I am now stuck as every attempt I make to resolve the situation is blocked by a request to enter an admin account and credentials that I no longer have. Why did Windows allow me to do this? Windows should not have allowed me to eliminate my only admin account.

I assume that my only solution is to reinstall Windows. Can anyone confirm this?

Any advice to run tools that require admin access is of course not going to work, because I have no credentials. Fortunately I do have Windows 10 installation on a flash drive which I created a few weeks ago.

Thanks in advance for any assistance

Download Hiren boot disc, you'll need another computer to create a bootable USB. Boot to hirens and use lazesoft tool and enable the built-in admin account and grant your other account admin rights.

Thank you but I have now found a simpler solution.

1. Execute a safe boot with command line access;
2. Login to built in Administrator account;
3. At command prompt execute command "net localgroup administrators MyAdminAccount /add";
4. Then restart and elevated rights have been restored to MyAdminAccount
