I recently installed Vista Enterprise RTM on a system I built a few years back. Vista failed to recognize my Linksys PCI Wireless card and my motherboard’s AC-97 audio chipset, but when I ran Windows Update it automatically downloaded the drivers, installed them, and rebooted.
Oh wait. It didn’t reboot. The hardware… just started working. Sixteen years of rebooting after every single update, trivial or otherwise, have finally come to an end. Yay!
