I still cannot firgure out what advantage that has, please help! (This is a serious question, I read the homepage and cannot see, why that matters? Thanks)
Sometimes you may want to erase information about devices that have been connected to the PC in the past. It is a privacy issue for most users, but there may be other reasons as well. Maybe you do not want your boss to find out that you connected your mobile phone to the work PC to update it, or copy mp3s from the phone to the work computer.
Well, in that case (such paranoid boss) there would be GPO in place that would NOT allow USB connection in first place.
I'm nor 100% certain, but I think that connection information is also stored in ShellBags, It might be something to check out.
