VERY wondered how to recover or reset a forgotten password in WindowsXP?

[Linda22]

Hello everyone.

My sister went on my computer while I was away and she's not too smart with computers and she changed all my passwords, for the main admin account, and administrator; I was wondering if there is anyway I can find out what they are? or can delete the account without having the reinstall windows. Right now I'm on a guest's account but I can't really do anything with it.

So if someone could please help I would be greatful.
Please and thankyou.

No. 
Here is the reason.
A savvy user will do all the safeguards to prevent others from getting into the system. That would include allowing only a guest account available.  But a careless person who does not know much might change a few things, but not all the passwords.

Is sounds like you sister knows what she is doing  and really wants to keep you out.
What did you do to get here so mad?

you might want to apologize for that time you gave a mohawk to her cat.

A repair install will reset the admin password.
