It's finally happened; Microsoft has today released to manufacturing the latest version of the Windows operating system which has been in development for five long years. Windows Vista marks an important milestone for Microsoft and as Jim Allchin said "This is a good day … An hour ago we signed off [on the RTM build]. We're ready to ship".
Keep an eye on the MSDN subscriber downloads as you'll likely see Windows Vista and Office 2007 there early next week. The MSDN subscriber downloads page today indicated that it would be down for upgrades late Friday. It's likely that Microsoft is anticipating some serious traffic on the site once those .iso images appear.
It appears that Windows Vista will RTM with the build number set to 6.0.6000.
