I just updated my laptop to windows 10, 1909 and when I try to sign in using my Microsoft account it says something went wrong and I can't even access Microsoft store

:)

 

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.

 

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?
