Locked out

[Mr Sejong]

So a few months ago I was given 2 desktops from a company that was upgrading all of their systems. I'm finally now getting around to plugging them in and trying to get them running, but all of the accounts require a password. Unfortunately the last IS that I'm extremely familiar with is XP, so how to get around this is new to me. It's running Windows 7 professional. I tried going into the boot options and entering safe mode, but even this required a password. When I try Switch User > Admin, i get account not found. But when I do Administrator, it tells me the password and username do not match. Does anyone know how to get into any of these accounts without downloading software (don't have a space pc) or without using the windows 7 OS disk (I only have the tower and monitor)

Thanks in advance
