Dell Optiplex 745 restore to factory settings

[Ecg28713]

I was given a Dell Optiplex 745 with Windows XP at my job and I work for a school. So it requires a login when it boots up, but I don't have the password. Also I do not have any boot discs or OS discs.
Is there a way to format or restore it to factory default?

many dells have a built-in factory restore if you hit F12 off a fresh boot while on the Dell splash screen, though why you would want to restore to XP, a system long dead, that is full of security holes now, I'm not sure.

Boot from a CD/DVD/Flash Drive to install Linux or a newer OS.

It's not that I want to boot to XP it's just that I was given a new computer and I can't afford a new one. I'm not very familiar with Linux, but I would be willing to give it a try.

I had a Windows Vista OS Disc laying around from an old computer that worked.
