The command prompt is an invaluable tool in Windows. It earlier versions of Windows, such as Windows XP, it was possible to maximize the CMD to full screen by pressing Alt+Enter. However, if you try this in Windows Vista/7/8/10, nothing happens! You can increase the size of the window by dragging the corner but only to some extent. You cannot increase its size after a particular size. Maximizing the window only causes the CMD window to occupy half of the screen.
In Windows Vista, if you hit Alt+Enter, you may see the message: “This system does not support full screen mode.” In later versions of Windows, you not see even this message. Hitting Alt+Enter does nothing!
No full screen
In recent versions of Windows, the device drivers do not support all the DOS video modes. Due to this, the CMD or any other DOS program does not get maximized to full screen. The device drivers are based on WDDM (Windows Display Driver Model).
It is possible to solve this problem by installing the Windows XP version of the video drivers for the video adapter present in your laptop/desktop. However, this method is far from perfect and you may not be able to run Aero, or the resolution of the screen may not work properly.
If you are using a recent version of Windows, you will have to live without CMD in full screen mode. However, there is a workaround. It only makes the CMD window fill your screen. This is not full screen that we were used to in Windows XP and earlier versions of Widows. It is just a maximized window occupying the whole of your screen.
Here is how…
Type cmd in the start search box, right click on the cmd shortcut and select “Run as administrator”.
Type wmic in the command prompt and hit Enter.
Maximize the window by using the mouse. The cmd window will occupy the whole screen.
Type exit to quit wmic. You will be back to the normal command prompt. Now you have cmd in full screen!
Alternatively, you can also change the buffer size and window size.
Open cmd and right click on the title bar and go to ‘Properties’.
Select the Layout tab and change the Screen Window Size and Window Size according to your screen resolution. Click OK and the CMD window will now occupy the whole screen.
