"If you forget your password on a computer that is part of a workgroup or is a stand-alone computer, check your password hint. (Your password hint is located on the Welcome screen beside the password prompt.)"
"If your password hint does not help you remember your password and you did not create a password reset disk, you will need to have someone with a COMPUTER ADMINISTRATOR ACCOUNT create a NEW password for you. For security reasons, a computer administrator cannot recover your password if you forget it; he or she can only create a new one for you."
It looks like something the comp admin would have to take care of. So what it sounds like is that if someone, other than your sister, is the main admin of that computer, he or she should be able to create a new password which would allow you to access the comp.
