The same issue in 2018.2.20. Is it Unity bug or Win10 bug?

Seeing this issue in 2017.1.0p4
Even tried to handle the window ourselves using user32 calls, but it seems as if Unity keeps overwriting the window to not allow touch input when maximized.
It also seems as if the window gets reset when you reach a certain size, and then it can't be dragged anymore via touch input.
Will this be fixed anytime soon?

We also notice on the Lenovo that the maximise, minimise and close buttons are non functional from the moment the window is opened. Unity 5.3.8f1

We also got this problem and I haven't found a workaround either. We create our app for Touchscreens so we really need to have this fixed

I've ran a series of additional tests on this issue as it's pretty critical for us. I've been unable to find a suitable workaround so far.
1) Everything works correctly with a mouse. All the issues only affect touchscreens.
2) You cannot drag the window at all.
3) You cannot use the icon menu (left of tittle bar) at all.
4) You can only resize the windows by dragging the right and bottom borders (left and top do nothing).
5) Minimize, Maximize and Close all work before maximizing. None do after.
6) Clearing PlayerPrefs from the registry fixes Minimize/Maximize/Close for the next time you start unity.
7) Changing "Screenmanager Resolution Width" in PlayerPrefs in the registry can fix Minimize/Maximize/Close for the next time you start unity.
8) Clicking Restore with a mouse while the window is maximized restores the Minimize/Maximize/Close behaviour.
I feel like all these bugs could be symptoms of the same issue. I also believe this affects all non-fullscreen standalone Unity apps, when running them on Windows tablets/laptops with touchscreens.
We're using Unity 5.3.2 for this particular project.

We're running into the same issue over here. I'd like to add that clicking the buttons on a windows title bar works (using a mouse). Touching them does not (via touchscreen).
