How to minimize
In all 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 will remain 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 of the window.
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.
Tip: Clicking on any program icon on the taskbar that is minimized will restore the window.
Note: 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 as big or small as you want on the screen.
Minimize keyboard shortcut
In Windows XP and earlier versions of Windows, you can minimize windows only using the keyboard by pressing Alt+Spacebar. And in the window properties drop-down menu press N to minimize the window.
How to minimize all windows and get to the Desktop
When you minimize a program, it shows any other open program that was behind its window. If you want to minimize all open windows at the same time, there are two methods:
Method One - Press the Windows key+D on your keyboard.
Method Two - Right-click the time and date in the lower-right corner of the screen (above A) and select Show the desktop (B) from the menu that appears. Or, you can click the very small tab on the far right side (just left of C).
