Windows 10: Why did MS changed my login to "New User" to my MS linked desktop computer disabling my...

MS has disabled my ability to access my MS linked desktop by changing my login screen on the desktop to "New User" and asking for a password, which has never been setup anytime before for a "New User". No additional user option is being provided. What is happening? How can I resolve the issue?

Login not accepted for my MS Account

Let me explain, again, what I have experienced:

• I use my MS account to unlock this computer. No problem doing that
• I attempted to use other apps requiring the MS login, like Outlook, or even this forum, and it would not accept the very same credentials I used to unlock the computer
• I used my wife's MS account to login to this forum so that I could seek help
• I have tried resetting my MS account twice, and that did not work either.

I would appreciate suggestions OTHER than wha I have already tried

 

MS online account logins VERSUS W10 computer login passwords

I am configuring a new computer. I would like to use a shorter, 7 char computer login password, but it seems that MS in W10 requires the same password for the MS online accounts, like this community and other centralized capabilities, as the login password
for my computer. The MS online accounts must be at least 8 characters.

Why can't I establish a completely different password for my computer and the online accounts ?

Please let me know if there is a way around this apparent rule.

If it really is a rule that the computer password must match the MS online account passwords, then

I would suggest this is a counterproductive restriction in a world where password management is already burdensome.

 

Unable to finish change of primary (login) email to MS account

I have personal MS account without Office 365 and other pair services. Only for Windows logins. I had old email "A" and now i have new email "B".

So i changed email address:

• add new contact email "B"
  
• set "B" as primary alias
  
• deleted "A"
  

So i now see only primary alias address "B" and my phone number under contacts (login aliases) in my account administration. On that screen there is nothing about old "A" address now.

But! When i go to some MS login (one drive, MS online account, ..) i enter "B" as login and it is recognized well. BUT - instead of password input some "verification code" is sent to old address "A" - BUG!

Side note: it is lucky that old "A" email is still working for me.

I am totally lost in neverending FAQs and no way how to fix it. Please help me how to eliminate old "A" email address as contact and login address.
