HI there. If you forgot your username and password try login with the administrator account. Username is administrator. Usually the password is blank. After that you can reset your passwords from Control Panel, User Accounts section.

If at the logon you use the welcome screen, hit twice CTRL+ALT+DEL, after that you can type administrator in the username textbox.

Please tell me if that solution was helpfull.
