Why does Vista try to install drivers for a USB flash drive? Shouldn it just open automatically?
It isn’t necessarily Vista. In fact, all versions of Windows install some kind of device drivers particular to that hardware. They do that in order to communicate with the piece of hardware. In your case, for example, you will get the notification of installing such drivers when you plug it in the first time. It just initializes your USB flash drive for use with Windows. Vista is just a bit more descriptive in this regard. Try unplugging your flash drive, and re-plug it. This time, it will not install the drivers because it automatically detects the drive and “knows” about that device. Hope this helps!
