A friend of mine pointed me to the article The Windows Vista Developer Story: Application Compatibility, Migration, and Interoperability quite some time ago (shame on me for not mentioning it earlier). It is a very useful resource when you have to deal with adapting existing applications for the changes that come with Windows Vista.

Topics of this article include:

• Thirty-Minute Compatibility Check
• Operating System Versioning
• User Account Control
• Windows Resource Protection (WRP)
• Internet Explorer Protected Mode
• Windows Vista 64-bit
• Microsoft Graphical Identification and Authentication (GINA)
• Session 0 Isolation
• Networking: TCP/IP Stack and the Windows Filtering Platform
• Networking: Kernel Mode IP Helper APIs
• Networking: IPv6
• Compatibility Risks
