In previous versions of Microsoft Windows, the System Preparation Tool (sysprep.exe) was found in the Deployment.cab file on your product CD. If you’ve examined the Vista DVD however, there’s no such cabinet file present.

You can run the tool either from the command line using various switches (type sysprep /? to learn more about these) or you can double-click on the executable and run the GUI version of the tool.
