(Microsoft is doubling down on Azure and DevDiv, if anything.)
This seems only to put the desktop at risk, especially with (EdgeHTML-powered) HTML+CSS+JS as the "third pillar" of the original Universal Windows Platform strategy, this only seems to further feed questions about Microsoft's overall confidence in UWP and thereby that middle word, Windows itself. This decision is directly showing a weak flank to "Chrome OS". What's to stop Chromebooks from attacking Windows for just being the junk drawer of old Win32 applications and games around a Chrome OS knockoff?
There's certainly still a lot of value, especially in enterprise, invested in that "junk drawer", but is that enough any more? Yeah, there's just no way that this decision is doubling down on "desktop dominance".
That’s all Windows has been for years. There hasn’t been anything interesting happening nor any serious money invested in writing PC software for well over a decade. The only non game companies making any money selling desktop software are Microsoft and Adobe.
Even from a corporate standpoint, enterprise deployments of desktop apps are cumbersome. That’s the reason that even corporate LOB apps have moved to the web. Besides a web site is the ultimate cross platform app.
