How do you hack into a anther administrators account?

Question

my sister and I have two administrators accounts on our PC.she has put a password on hers.Obviously I can remove it and go but is there a way to hack in to her account without her knowing it.

Answer 1

crack it! try using Cain and Abel!!! Brute Force Attack might take some time, Dictionary attacks are faster, cryptanalysis attacks need tables.

Answer 2

I have a problem believing the reason you want to hack into your own computer.  If you mess this up she will be locked out and know what you were trying to do.  Is it worth it?  Tsk Tsk

Answer 3

Use a keylogger.
