A few months ago I lost my Administrator privileges on my own PC. I believe I encountered this issue when trying to change my account username and during it accidentally changed the account permissions.
So far I have tried the following to fix this issue:
- Going to Family & Other Users to change the account permissions (the tab does not show up)
- Access administrator privileges through safe mode (asks for the built-in admin password)
- Boot the computer through a USB with using a Password Refixer (was unable to as I could not pay for the software)
- Fixing the issue through Local Group Policy Editor (local users and groups tab does not show up)
I have also considered booting the computer through a USB with the windows installation media on it and use Shift + F10 to solve the problem from there.
I am wondering if there is any free and safe way that I am able to regain my administrator permissions on my own PC. I have been working on trying to fix this for quite a while now but have been unable to find any success. Your help would be greatly appreciated on this issue.
