Microsoft has improved the dictation capabilities of Windows in the latest feature update.
While running Windows 10 April 2018 Update (1803) or better and a PC with a microphone, and in any app or text field, press the Windows key + H on the keyboard.
This brings up the dictation bar at the top of the screen and you can just begin talking.
When done, simply close the dictation bar with your mouse or tap of the finger, or say: “Stop Dictating”
