I would recommend that you go out and buy one, or contact the manufacturer of the PC to see if there is one that they can send you for all your PC's so when an employee leaves you can remove the OS and then start new to prevent security breaches.
But to change the passwords you can use The Ultimate Boot CD
and the password recovery tool that is on there.
ISO Recorder Canned Speech:
Here is how to use ISO Recorder which can be downloaded from Here
. Just pick the version right for your Operating system and computer.
1) First install it which is rather easy compared to most programs. There are no Free Applications bundled with this like toolbars and such.
Installation Step Two where you pick the directory to install it to, and the access level. I would select the default attributes.
Confirming that you want to installation.
2) Selecting a file to burn. You will need to right click on a a file as seen below and select copy image to CD/DVD
3) Options window for ISO Recorder I would suggest leaving the default values checked or selected.
4) Progression of Burn.
5) Completion of Burn.
As you can see this is a very easy program to use and master.
