On setup's "Complete" dialog, there are a bunch of links offered in "Supplemental Information" at the bottom. I have noticed a few issues that are kind of surprising.
Under Microsoft Update, it says:
For information about how to use Microsoft Update to identify updates for SQL Server 2008, see the Microsoft Update Web site <http://go.microsoft.com/fwlink/?LinkId=108409> at http://go.microsoft.com/fwlink/?LinkId=108409.
This goes to:
Which is just the main page for Microsoft Update, and on most operating systems (Vista & Server 2008), it simply tells you, what are you doing here, go to the control panel. There is certainly nothing SQL Server-specific on this page, never mind geared specifically to SQL Server 2008.
Under Documentation and Samples, it says:
To read about support for SQL Server sample databases and sample code for SQL Server Express, see Databases and Samples Overview <http://go.microsoft.com/fwlink/?LinkId=110391> on the CodePlex Web site at http://go.microsoft.com/fwlink/?LinkId=110391.
This ends up at:
Which has the 2008 CTP updates to sample databases from Febraury of 2008. However, the page does not seem very Express-specific, as I would have expected based on the description of the link. In fact I even see several mentions of items offered on that page that are NOT supported on Express.
Near the bottom, it says:
For more information about late-breaking changes in this release of SQL Server, see the latest readme file <http://go.microsoft.com/fwlink/?LinkId=100093> at http://go.microsoft.com/fwlink/?LinkId=100093.
This link goes to
Which contains a download for the readme file for RC0. Unfortunately, this was an RC1 setup package. I hope the RTM setup package points to a link that contains an RTM readme file.
