There’s a great post on the Windows 7 team blog by Yochay Kiriaty entitled “Is Your Application Ready for Windows 7 RTM?”. It not only covers common compatibility issues but goes on to discuss optimising applications for Windows 7, taking advantage of features like the new taskbar, libraries, power optimisation etc.
In fact Yochay has done a series of Windows 7 posts / videos on Channel 9. Worth checking out if you haven’t seen them already.
And of course Eric interviewed our very own Dave Allen on this very subject some time back.
