The best thing about this option is that it covers a vast amount of icons and also has a very simply created icon pack.
The icons are created with gradients which makes them more colorful and will improve the appearance of your desktop screen. This icon pack is a great option for Windows 10 as you can choose to customize the icon color to fit with the windows 10 OS theme.
Topping my list is Lumicon, a well-designed and advanced icon pack covering all popular desktop icons, browsers, and media icons.
