Normally, you could launch Command Prompt with default privileges by simply clicking on it in the search results list, or highlighting it with the keyboard and pressing Enter. Alternatively, you could launch Command Prompt as an administrator by right-clicking on it in the search results and selecting Run as Administrator.
But for the fastest experience, highlight the Command Prompt result in the Windows search bar and press Control-Shift-Enter. Doing so will automatically launch Command Prompt with elevated administrative privileges, and you’ll see the User Account Control (UAC) prompt appear immediately as a result.
