I think you're forgetting some things:
There's the 'flat design' bullshit that people think 'is artistic':
Worst of all? This shit is starting to infect traditional desktop computing too.

Are those buttons on that dialog box or just text decoration? Who fucking knows?! The only help you get is the layout of the window.
Now look at Windows NT 4.0:

You know that "About Windows" thing is a dialog box. It has a shaded "OK" button in the right bottom corner. Shit's 10/10 UI design.
Besides. You can actually see that the buttons to close/minimize/maximize a window are actually buttons, in contrast with Windows 10 where they're decorated like they themselves are window decoration.
Windows NT 4.0 literally indicates what is and isn't a button better than Windows 10!
Hang on, guys. I think I'm gonna install Windows NT on my system.
