The build is really a mess, as if I needed more pressure, I will stay on the next RTM build when it comes out and leave the insider program. I’ve no idea how they screwed up menus, given the fact they’re a computer giant, their insider builds shouldn’t have such silly issues, I expect new features to get broken not old ones, oh well.
Edit: I just reinstalled Windows and I won’t use insider builds ever on a stable PC again. Stability is top priority.
