There’s nothing in particular wrong with Win32 (or its 64-bit sibling) other than its singular suitability for the platform for which it was designed, but it doesn’t lend itself to a Windows Store or mobile devices (which is a feature, not a bug, to some of us). Less Win32 just means more UWP, more “app,” more mobile user interfaces on a platform that’s nearly wholly desktop-oriented (laptops with touchpads count as desktops it’s the discrete pointing device or lack thereof that defines the UI type). I’m not interested in a non-win32 Windows even if it did have the tinkering room Win32 has. The new ways things are done make it very difficult to achieve the same customizations.” “Each new version of Windows moves further away from the classic Win32 programming model, which allowed room for a lot of tinkering. That’s what makes part of the farewell announcement from (former) Classic Shell dev Ivo Beltchev so ominous: I’m with you on the bit about not wanting anything to do with UWP apps.
