The Windows Vista Developer Story: Application Compatibility Cookbook


MSDN has a Vista developer story series on how to develop applications for Windows Vista.


http://msdn.microsoft.com/windowsvista/downloads/docs/developerstory/default.aspx


One of the particularly useful articles is on Application Compatibility


http://msdn.microsoft.com/windowsvista/downloads/docs/developerstory/default.aspx?pull=/library/en-us/dnlong/html/AppComp.asp


(also at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnlong/html/AppComp.asp)


It details many of the changes in Vista and how to change your application to comply with the Vista paradigm.


Definitely worth a read.
