The first thing you’ll probably notice is that the minimize/maximize/close buttons in the top right corner are not colored.
Notice on the image above that just like its name indicates this theme follows a blue glass design. Soft Glass 10 is a Windows 10 theme that mimics the Windows 7 theme design, but it also changes things up a bit. Taskbar transparency is activated and the aforementioned Windows 7 wallpaper gallery starts being changed (slideshow mode), just like in Windows 7. You still get the same tiled Windows 10 menu. Keep in mind that only the Start Menu icon is restored, not the menu itself.
Alongside with the theme you also get all the Windows 7 wallpapers and the Windows 7 Start Menu icon (the famous orb) gets restored.
