And, I couldn't figure out how to uninstall it! It wasn't uninstallable in the normal ways, and I don't think I ever figured out how to do so.
I won't miss Paint, and I never used it, but I definitely don't consider Paint 3D an upgrade or improvement. And, I really hate Microsoft's standard practice of replacing file associations even if I've already setup my own before one of their apps gets installed (I had a couple of other tools setup for images, and they got replaced in the defaults for like 30 file types). They do it with pretty much every app they distribute. It's presumptuous.
