If you intend to transfer a Windows image to a different computer, you must run sysprep /generalize, even if the computer has the same hardware configuration. The sysprep /generalize command removes unique information from your Windows installation, which enables you to reuse that image on different computers. The next time you boot the Windows image, the specialize configuration pass runs. During this configuration pass, many components have actions that must be processed when you boot a Windows image on a new computer. Any method of moving a Windows image to a new computer, either through imaging, hard disk duplication, or other method, must be prepared with the sysprep /generalize command. Moving or copying a Windows image to a different computer without running sysprep /generalize is not supported.
