Vijay Raj, a Setup & Deployment MVP from Bangalore, India, authors a popular blog on Software Development & Deployment at http://www.MSIGeek.com.
To aid migration to Windows 7, Vijay has authored a 5-part series on Windows 7 Application Compatibility. AppCompat is one stop point whenever someone wants to move to a new operating system (in this case, Windows 7).
This series of posts covers information on how the core changes of Windows 7 will affect the Day-to-Day applications. It also covers methods to mitigate these issues from the basic viewpoint of Developers, IT Pros and End-Users. Highly recommend!
