Solve : Login problems with used computer?

1.	Solve : Login problems with used computer?
Answer» I got a used computer from our local Catholic SCHOOL, and the login screen won't let me login because the username and corresponding password from the school students is still required. How can I override that?Since you got the computer used I would recommend a format and REINSTALL of windows. I hope you received a windows install/recovery DISC along with the computer.What Windows version?
