I have two accounts "user1" ("user" level and I know this password) and "admin1" ("admin" level)accounts. Built-in administrator account has a password (I know this password) but it's not active. I changed my admin1 password and now I can't remember it.
I have tried to use built-in administrator account by "safe Mode" but it doesn't shows up in the list of users (to log in safe mode)? I logged in as a user1 account with cmd prompt. I typed "net user administrator /active:yes" but OS says "System error 5 has occurred. Access is denied". How I can use built-in administrator account (since I know that password) when it's not activated?
