I see you're an expert in Windows. I have the same problem. Tried all your solutions and probably all solutions from the google. I tried Account Troubleshooter - it doesn't show any problems and it says that I need a Microsoft account (obviously). Also I refreshed Windows and the problem exists even during first user configuration. It still cannot connect my Microsoft account. I see it's common problem. Can you help, please?
