Mate I already said that there's no option of manual forcing. Just right click, and "Troubleshoot Compatibility". I just selected this option for the program which wasn't working, and OS automatically suggested "Win XP SP2" as compatibility mode & Voila!
Dude Ive seen my brother running age of empires III on W7 HP on his laptop in compatibility mode. He had could select Win Xp sp 1 sp 2 sp 3 win 95 etc...
Windows XP Mode is different from Windows Compatibility Mode.
Compatibility Mode - Present in all versions of Windows 7. Most newer software that runs on XP (32 bit stuff) will work with this mode ( if it doesn't automatically run on Windows 7, i.e.).
Windows XP Mode - Only in Windows 7 Professional, Enterprise and Ultimate. Requires a virtualisation enabled CPU and virtual machine software (like Windows virtual PC). 100% support for everything that could ever run on XP. Useful if you have older 16 bit exes and dlls which don't run even in Compatibility Mode.
