When automatic updates are set instead of choosing when to download and install the latest Creative drivers
or even for other addon devices if allowed to go on will trash a working installation even if the latest are already on!
I see that with ATI drivers as well where the drivers alone are in the update while you already have the latest Catalyst installed with the same drivers. When waiting to look over the optional updates as well as the regular security fixes and WDefender updates I simply download the MS only for Windows not for any hardwares there.
Another thing to add here is that Vista updates were seen then for the Audigy 4 series card while lately some are still running the Audigy 2 models on 7. Apparently they finally got around to getting Vista or 7 updates for those out pointing to what you were saying there.
