The images Monce shared shows how well the upcoming software scales to different screen sizes.

On the Lumia 950 XL, which features a 5.7-inch display, Windows 10X’s taskbar fits wells at the bottom of the screen, while the quick settings panel pops up with all the elements in place.

Monce said Windows 10X responds well to the smaller form factor, as the images demonstrate, but plenty of work still needs to be done from a usability standpoint.

Windows 10X is expected to be a lightweight take on Windows 10.

As something that will likely be targeted at enterprise and education customers, Microsoft’s new software could be primed to have a breakout year.

As we’ve said before, Windows 10X won’t be something you’ll be able to upgrade your existing machine to.

Wouldn’t it be cool if Microsoft allowed old Windows Phone owners to download a working version of the software on their device?
