2026-09-27T16:51:15.72+00:00 The answer was in my initial post.
A 5+ hrs. slog with the massive help of AI.
The AI understood how MS applies update, Office 365 and the telltale signs of what happened and my prompts.
Also, I had the original software downloads and product key. But do not be fooled, this was NOT a case of simply deleting reinstalling software.
