Why can't I use desktop apps with my note 7 when using Dex?

[Android Central Question]

It is really dumb that neither android or windows, the both specialized in either phones or desktop experience, haven't made these great functionalities. Windows just seems like a concept, and very lackluster in many areas. You can even get a better experience of Windows on Android with Squarehome 2, with widgets, cubes, and home screen editing locks. So disappointed in one and the other for not collaborating. We could use phones and docks at home, and laptops and desktops for work/lab/school experience. Enough said.
