Minimize Icon

Alternatively called a collapse box, minimize box, and minimize button, minimize is an action in GUI operating systems to hide a window, but keep the program running in the background.

How to minimize

In recent versions of Microsoft Windows, the minimize button is represented by an underscore or dash in the top-right corner of the window. When minimized, the program remains on the taskbar, but not visible. In the early versions of Windows 3.x and other operating systems and software programs, the minimize button may be represented by a small down arrow.

The image below shows an example of a window in Microsoft Windows with the minimize button in the top-right corner.

Where do minimized programs go?

In Windows, when a program is minimized, it may seem as though it has disappeared. Fortunately, that is not the case. Minimized programs may be located and accessed from the Windows taskbar, which is located at the bottom of any Windows desktop. The following image shows examples of various Windows taskbars containing minimized programs.

Clicking on any program icon on the taskbar that is minimized will restore the window.


Some programs may be minimized to the Windows Notification Area.

Minimize vs. resize

If you want to keep the window open, but not have it fullscreen, use the resize button to make it a window instead of fullscreen. Once set as a window, you can resize the window to make it bigger or smaller.
