File Explorer
The icons in File Explorer have been redesigned. They are flatter and simpler in design. The window border padding is thinner than previous versions. Windows 10 Creators Update and later versions come with a new Universal File Explorer (also known as the UWP File Explorer). Although hidden, it can be opened by creating a shortcut pointing to "explorer shell:AppsFolder\c5e2524a-ea46-4f67-841f-6a9465d9d515_cw5n1h2txyewy!App"
