I understand where you are coming from with the request for the driver updater. But honestly, I've tried so many over the years and just haven't felt totally comfortable just handing over the duties of updates to a program. I have crashed quite a few systems in the past with those. I am though always curious as to what they find, but then I performed my checks/updates manually, except Microsoft updates of course. That's the only thing they do right.
But if you should happen to find one you trust, then the 3rd party apps section in d7 is perfect for that. Just make sure it's portable and free if possible. Good luck. Let's us know if you find one.
