Windows x64 Editions have been out for a while, but I’m still seeing a lot of very basic questions in email and on the public 64–bit newsgroup, so I thought I’d post a couple of links to basic information to get you started.
The first is the Exploring XP x64 Edition column I did for the Expert Zone at the time of the release last spring. This is a basic overview of Windows XP Professional x64 Edition.
Next, an overall FAQ on x64 Edition, also hosted on the Expert Zone.
Finally, an updated Overview of x64 Edition webcast I did this month has some good general information, updates on problems we’ve seen since the release, and answers to some questions from the audience.
update: There's a new whitepaper up on the Microsoft site that you may find helpful: Is Windows XP Professional x64 Edition Right for Me?
