Have you forgotten your administrator password
on windows. I know I have and Friends have also.
Well ophcrack is one way of getting the password.
Obviously you could also try a utility to blank the password,
But they don't always work even though they say they have.
If you need further assistance with any of the programs please
goto links provided. They are not my programs they are all opensource.
All I have done is put them all together to make it easier to find.
