Windows 10 no administrator access
I just upgraded my laptop from windows 7 to windows 10. Before I upgraded, my brother created an account for himself and windows 10 seems to think that his account was the main one. He didn't have administrator access, so now I'm locked out of everything that requires administrator access.
When I try to install new software, the security pop up happens, asking for an administrator password, but there is no field to enter a password.
I can't open the command prompt (windows -> cmd -> enter)
I can't switch accounts, logging out lists no other accounts.
How do I get administrator access back, and how can I make windows stop thinking I'm my brother?
