Restore Factory Settings on a server without having the admin password.

Hi, I'm Barry Scott,

Recently I was given a computer from the business that I worked at which was closing down. I was planning on restoring it to factory settings but found out that because I'm not an administrator of the server at the business I wasn't able do this. I need a way to restore the computer to factory settings without having use the administrator password. I have the admin password but as I have taken it home it's not in the server range meaning I can't access it.

Is there any way of restoring the computer to factory settings without the admin being involved.

Thank you.

:)
