Assuming you're the legitimate owner/administrator of this system, you can use this utility:

Not for the faint-of-heart, but it works wonders.

Try the password cracker at www.seepassword.com. Let me know if it resolved your problem.
 
 

Thanks Sarah, seepassword.com is a real helpful site. Now at least we don't have to worry about loosing our passwords. And free software to block all those popup is really good. Thanks once again.

I have downloaded that software and it is working fine on my system. I am not sure if there are any particular settings required for that software on the system. But I don’t think there should be any problem in downloading the popup buster. If you don’t find it worthy you can always uninstall it later
