![]() And there is no reason to believe that Win32 apps have higher requirements when it comes to processing power and memory." You can easily build a crappy, slow, unresponsive WinRT app. Win32 and WinRT apps are not as different as you might think. "It all really depends on the quality of the programs. But allowing Win32 apps could have helped the chicken-and-egg problem the Surface is going to die from."Ĭlrokr doesn't agree with the argument that traditional desktop applications require more resources and consume more battery power than Metro-style apps, which might have led to Microsoft's decision to ban them in Windows RT. Microsoft wants devs to go through the Store and it is understandable from a money standpoint. "The reason I tried to disable Code Integrity has nothing to do with Win32 or WinRT," he said in a discussion thread on Reddit. "There are enough 'consumption' tablets already."
