As you may remember, I've regularly had crashes on my Vista box due to graphics problems. The latest NVidia drivers helped but there was still the odd BSOD. I've got the thing set up to do Automatic Windows Updates but today one of these wouldn't install so I went manually to the Win Update website. While there I noticed there were about 25 Optional Updates. Clicking to see what these were, there were ones dating back to March on there. Amongst them was an compability update for NVidia cards from several weeks ago. Because this was an optional update as opposed to a critical update, Auto Updates hadn't downloaded the fix to the biggest problem I was experiencing with the system! Well done Microsoft.
