  1. M$ does such a wonderful job of hiding the most important settings behind 20 thousand clicks and hidden windows… and often using gibberish like “9:40”. Why not use a time where it’s obvious that you are talking 24h time format, like 21:40???

  2. Thank You. The screen shot choices looked a little different by 2020-02-28, but I figured out that clicking on “Short Date” and choosing the one without AM or PM gave me 24 hour time.

  3. This was the Best

    I always had so much hard time finding the right way to do this and end up no luck
    Until today i found this 3 second fix

    Many thanks
