David, I would still update to 1903. Each update has updated security features and new features. If I remember correctly Microsoft does an annual major Windows update. The four digit number indicates the year and month of the update. 1903 is the update from March 2019. I was on version 17xx and went through two updates. First to 1803 then to 1903. I did not go directly from 17xx to 1903. I don't know if this is why I didn't have any trouble or not. But it worked for me.
