While working with multiple windows and applications on your computer, it is often beneficial to resize windows in a way that allows you to view more than one at a time. Although smaller windows are useful for this purpose, eventually you need to restore the windows to maximum size. Microsoft's Windows operating system includes built-in buttons that automatically maximize the size and eliminate the need to manually reposition and adjust the window with your mouse.
Click on the window you want to maximize so the entire window becomes visible and is not hidden behind other windows.
Locate the three buttons in the top right corner of the window. The "Maximize" button is located between the "Minimize" and "Close" buttons.
Click the "Maximize" button in the top right corner of the window to maximize its size.
You can also double-click on an empty space of the title bar to maximize the window. Some windows are a fixed size and cannot be maximized.
