Well here is my vote: NO driver-management-tool.
I can manage my drivers on my own. If anyone has to do a system-restore he will start fresh and new again and should not use "old" backupped drivers........in my opinion.
On the other hand...............keep the JV-Tools as slim as possible......
As it says in the title...........JV-Tools are there to clean the registry and stuff and nothing else.
As redseujac mentioned....enough 3rd-party-stuff about to do that job. :)
