Well, I've finished this entire thread. It's 10:28 PM EDT on August 2, 2024.
I see in the 3 or 4 pages since Simcha-Yitzchak's initial post about the Help question, that "Enabling Connected Experiences" (cute euphemism) has helped people access Help AND also perhaps fixed the update problem that triggered this entirrrrrrrrrrrrrrrrrrrrrre thread. So I might try that -- but not tonight.
I sympathize intensely with the heroic Pedro and Prius, and Don earlier, and anyone else who said that they were going to wait for MSFT to fix this.
But I might try the Connected Experiences tactic anyway, next time I'm on this PC, tomorrow evening or Sunday. I'll report back on what happens.
PS -- Someone earlier asked what use this forum was if MSFT wasn't paying attention to it. I'll tell you. It assures us that we're not going through this madness alone. It enables us to see other smart people try things. Sometimes great minds do think alike.
PPS -- I agree completely with the people who prefer perpetual licenses. But MSFT screws up even those. I'm so fed up with Win 10 and Office 2019 that I've paid someone to preserve my Win 7 PC with Office 2010 on it, and I'm going to keep it off the internet so I can always have a stable, familiar environment to fall back on when I need it for my long-term projects. I've given 35 years over to MSFT, but now they've clearly lost control of their products, and subscriptions and AI are going to make things even worse. Life's too short to spend my remaining couple of decades under the whims of MSFT's ineptitude.
