This was an early limitation, which was fixed in Windows 1803 with the release of the Windows.Graphics.Capture API. [1] That being said, your general point that there's so many ways to develop an app for Windows, and that not all of them support the same features, is definitely true. I think the general advice these days is that if you _can_ build your app as a UWP, do that. Otherwise, use the Win32 APIs as sparingly as possible, defaulting to the UWP APIs. Legacy apps are a bit trickier, and that's where Microsoft is investing in things like the Desktop Bridge (run Win32 apps in a UWP container) and XAML Islands (host UWP controls in a Win32 app).
