Is it possible to reset the administrative password on a Compaq that is running vista premium?

I have two operating systems on the compaq laptop, but the windows are secured with the admin password and user password. I can’t reinstall the os because I don’t have an installation disk.

Requirements

1. Windows Password Unlocker
An effective windows password recovery tool that lets you reset lost login password to Windows by creating a boot password reset disk. Windows and Mac versions are available.

2. A writable CD/DVD or USB drive to create the boot password reset disk
ACD/DVD drive is required for burning if you select to use a CD/DVD. If not available, please use the USB drive, but backing up the important data on it at first.
