A friend of mine has a Acer L5100 running Vista. During the loading of Update 955430 (which is a pre-requisite for SP1) the update failed as did the update for SP1. At some point after - i.e. a couple of months - another update has caused internet to stop working (the machine will not connect other than "Local Access only").
There are no restore points back before the failed updates. Removing SP1 was possible but did not solve the internet problem. I can't download 955430 to run it again because the machine won't connect and I can't download it using this machine because it just wants to install it. You can't remove 955430 either.
So how do you get an update from Microsoft when you have no internet connection?
