I meant that I literally did not have a visible Start Menu that I could interact with because Windows 10 uninstalled the version of Classic Shell[1] I was using as part of installing the Anniversary Edition upgrade. I actually had that message pop up, "Windows has uninstalled this program because it is known to be incompatible." Luckily there was an Anniversary Edition-compatible version available that I could reinstall. Note also that I don't especially consider Classic Shell to be an odd program given that when I briefly worked at Microsoft a few years ago (Win 8.1 was current), my manager actually recommended I install it on my second day there on the company-provided computer in order to retain the classic UI because that group found the Win8 touch UI to be unusable on the desktop.
