“Microsoft has a different version of Sysprep for each release and service pack of Windows. You must use the version of Sysprep specific to the operating system you are deploying. The differences are not immediately visible in the packaging and documentation of the service packs, so it is necessary to manually investigate.
The contents of the Sysprep deploy.cab file must be extracted to the Sysprep Directory on the VirtualCenter Server host. If the file downloaded from the Microsoft Web Site is a .cab file, the Installing the Microsoft Sysprep Tools appendix of the Basic System Administration guide details how to install the Sysprep Tools.”
