i bought a yard sale computer need to find password to access windows any ideas?

the computer i bought cost 10.00 bucks and was a donation but is still set up with their passwords any way to access windows?or should i scrap it?

reformatt it with a windows cd
How about installing a new Windows? Or get a new computer.
get a program called ERD Commander. you can crack just about anything you ever wanted to crack with it. Hell, I used it while I was in the Military to crack classified computers when dumbass officers forgot their passwords.... which were usually pretty stupid anyway... (ex: Raiders#1... and he was a mexican... no brainer there!)
if your computer protect by password i think u just need to removr the little battrey in mother card for few minutes and return it the password will be remove
if you start it in dos mode (it's probably that old) it may bypass the password need.
