To put it another way, Drew1903 is a User name with the # added for that; otherwise, no need or reason for it.
I sort of grasp using TM, although, for my own use, I won't bother. IF an unexpected closure Edge restores all that was open. If I am closing, it asks if close all or not. When rebooting, all tabs/sites there were, still are (again). Same for whatever apps were going.
As for your issue with Automatic Updates... they are not "imposed" nor are they "without your permission". You bought a license for an OS that is SaaS, which includes Auto-updates. Said arrangement carries with it an awareness of what's coming, while you are using the license. And the timing of Restarts is well in the hands of the End-User, allowing time to "be organised" before a reboot.
Cheers,
