Calin, For your questions, the wizard will be disappeared automatically once you update your "Other devices" with actual drivers. AFAIK, there is no other workaround to prevent the wizard to pop up when a new device node is detected in the system.
Actually, the point is that you should not to uninstall your drivers when you uninstall your program if it really involves the hardware. When uninstall your software just remove your value-added applications not uninstall drivers. Then later when you install the newer driver, it will update the existing drivers. That is what is recommended by DDK. Take a look at what DIFx can do for you and make use of it.

None of the parameters can do it. I guess I have to ask this question in a forum; The Wizard appears in XP, but not in Server 2003.
