The Windows Vista Service Pack 1 Beta has this week been put through to the release candidate stages. After trying the last few Beta builds i agree that the service pack is a worthy upgrade and as you would expect it fixes a fare amount of bugs and makes Vista preform a little faster. The RC was release to 15,000 testers as part of a private beta program. I will be writing a full review when over the weekend when i manage to get a copy of the service pack installed.
