I've just formatted my computer and have re-installed Vista Business 64bit. I've got everything up and running, and have got all the latest updates from windows update. However I've just noticed that I don't have SP1 installed. I've refreshed windows update and it says that my install is up to date. What happened to SP1? 
I had it on my old install before I formatted. Any ideas?
Thanks.
