There’s a new stopwatch feature in Windows 10 and I love it! I was doing some performance testing and I needed to know how long a particular task took. In Windows 7, I would have clicked the time icon in the system tray, recorded the time, performed my task, recorded the time again, and then calculated the difference between the two times. When I asked Cortana for a clock to perform the same steps, I discovered the new built-in Alarms & Clock application.
Then I tried the new stopwatch feature. I love it! My task ended up taking 2 minutes and 53.55 seconds to complete. With a few changes to my task, I got it to complete in 7.13 seconds! Nice!!!
