Windows 10: Constant "Microsoft Account Problem"

I apologize if this is in the wrong section of the forum. Mods, please move it if necessary.

I keep getting a notification of a Microsoft Account problem (password change, etc). I keep fixing it, but it keeps coming back. Is this possible malware doing this? Or something with the new version of Windows? I am updated to 1903, and this has started since the upgrade.

Thanks for any help.

Cannot link/add my Microsoft Account to Local Account


Hello Ken,

Im using Win10 Build 1607 with all latest update.

I also run all related troubleshooters:

• Windows Update
• Store Apps (says i have to login in my microsoft account but thats the problem, i can't)
• Microsoft Accounts

No Problem found. Also the suggestions from Microsoft didnt helped.

 

Remove account


I suggest you backup your personalized files first before removing the account.
To delete an account, follow these steps:

1. Press WIN + X keys and click Command Prompt (Admin) from the menu.
2. Type the following command and press Enter. Replace test with the name of your sister's account. Code:
   
   Code:

   net user test /del

 

Cannot sign in microsoft account.

My device: Lumia 520. GDR2.
I cannot sign in my Microsoft account on my device. It didnt say any error but Microsoft account is not listed in Email and account list. When I click add button, it will show microsoft account option but after press sign in, it is still not shown in email
and account. Another problem is i cannot delete facebook account. Error code: 0x83cf1202. I have tried as suggested here: http://support.microsoft.com/kb/2475837/en-us#step0x83cf1202 but as my Microsoft account is not shown, I cannot do step 6.

Any suggestion?
