Only 1% apps successfully get installed in that mode. The installation of older apps in compatibility mode is seemed to be an eyewash. Windows 10 is an immature OS with a lot of backward compatibility issues. And once I upgraded to windows 10 my IDT sound driver, Alfa AWUS036H and so many other apps were corrupted / defunct. And at that stage it gave me 1 incompatibility issue with an app. I carried out compatibility test with my already installed apps and drivers. I had no issue on my licensed Windows 7 Home and before upgrading to Windows 10. I think Windows 10 was released in a haphazard way by Microsoft even when there were so many bugs yet to be removed after getting feedback for technical preview version.
