Hello battlegorge,
All computers (built by large manufactures) that come with Vista Pre-Installed, come with windows reinstall or restore software. The software may be included on a CD that came with the computer or may have come on a hidden partition on the computer's Hard Drive. All manufacturers include the software differently, so please consult the documentation, that came with the computer, or contact the computer's manufacturer for assistance in finding/using the software or in ordering a replacement copy of the software.
Thank you,
Darin MS
