Please be so kind as to review the thread for this post.
The beta version I had downloaded early in May, '22 worked nicely. In the time since, I would receive notices that Start11 updates were available, but not wanting to experience the issue again, I avoided installing them.
Well, I guess I shouldn't have, but last week, I downloaded and installed the version 1.39.1 update, and now, again, the menu that randomly displays after power up is the native Windows 11 menu. I need to type Start11 in that menu to bring up the S11 screen, where I click on the already-dark radio button for "Windows 10". At that point, the Start11 menu is reinstated.
I power my PC down every evening, so now, when I boot up the next time either the Windows11 or the Start11 (as Windows 10) comes up. I have detected no pattern.
I don't have a version number for you of the one that this most recent update replaced, but upon searching my downloads folder, there are Setup items for versions
I can't think of any other diagnostic observations I've made, but if there's anything specific you'd like me to check, by all means let me know.
