This Minimize Window icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,100 icons, all in the same style and quality.
This is a very simple icon that is composed of a square with slightly rounded corners. Inside the square is a thin rectangle with rounded corners. It is placed near the bottom of the larger square to represent the handle of a window.
