ive lost all access to my only admin account! a year ago i tried to hide my account(to have a text field logon like in xp) by changing the registry value to '0'. it didnt do anything. everything just went on as normal, account not hidden and no text logon. well a few days ago i made an account for my grandpa, not an admin just a standard user. well when i went to logon to it to set up everything my main(and only) account was no longer visible. i think if i put the registry value back to 1 ill be able to log in. the problem is i cant edit the registry on this standard user account. ive tried booting into safe mode but it still puts me on his account and im unable to get on my account. plz help as i have important documents on my account!
