When we took the decision for the lowest Windows version Notepad.net could use, it was fairly simple, the current version. The problem is, at present, that’s only 12% of users; why are so many people not updating Windows? well, it appears it’s actually Microsoft that’s preventing it, we have machines here that are “up to date” according to their update panel, but still on 1803. We had to start somewhere, and some of the features we use are 1809 onwards. We hope 1903 will be a more stable and prolific roll-out so everyone can get access to our apps.
