Recently I needed to update some clients running on Windows XP and WIndows server 2003 as well as Windows Vista. After some searching I came across a post from Augusto Alvarez. He mentioned that by default WSUS only receives and distributes drivers that are digitally signed by Microsoft (meaning that the driver was fully and properly tested by Microsoft). It’s a bit strange in a way because the update’s I was searching are signed by Microsoft.
Anyway I did follow the guidline from Augusto and I did found the Feature Packs.
