Developer Information for WinXP SP2

So, the much awaited Windows XP Service Pack 2 RTMed Friday, and by now should be available to download from the Microsoft Download Centre. The MSDN site has a comprehensive set of information for developers about the changes introduced in this update. Use this index page as an inital jumping off point. I highly recommend starting with the Overview White Paper to get a summary of the changes, before delving into some of the more in-depth information.
