The API is very stable. Any Win32 app from the last 24 years will still run. 16 bit apps will still run on the 32 bit version of Windows. They promote the cool new thing every so often, but all the old stuff still works and eventually gets the access to the new features.

Win32 is super stable. The .NET Ui toolkits churn every 3 years or so without much improvement. Very frustrating.

I haven't seen much (if any) churn in Windows Forms or WPF toolkits in about a decade. Are you sure about that 3 year thing?

i meant every 3 years there is a new, incompatible toolkit. Winforms, Html5/JS, WPF, Silverlight, WinRT, now UWP. Instead of refining what they have they create something new (possibly with less capability like WinRT), and put the previous toolkit into maintenance mode with only minor development.
