1. Open a new command prompt window by launching the
appropriate shortcut from the Start menu or page. You can also type “cmd” and
press Enter into the Start menu search box. Your command prompt should launch
as usual in a resizable window
2. Inside the command prompt, press both ALT + Enter
keys. This now makes the command prompt enter
into full screen mode
3. You can press ALT + Enter again to switch back to the
smaller, resizable window mode.
The same key combination works when using command prompt
with elevated credentials.
