Previously used Zenworks 7 with sysprep to image Windows XP Pro machines without issue. Each machine would be unique and register to Zenworks, worked great. We had one image that worked on all machines regardless of vendor. Now with ZCM 10, the process doesn't seem to be the same. Is there a current guide somewhere? I have searched the forums and cool solutions and just can't seem to find that one guide that covers it all.

Do I still need sysprep with ZCM 10?
Do I need to unregister the machine first and uninstall the ZCM agent, removes registry keys, etc. which some of the documentation I have found indicates?

Surely there is an easy way?
