Windows 10: "We can't sign in to your account" error message

It all started with my local repair computer system format on my laptop and when I change c/users/username in Windows 11 to my real name and I restarted, that was when the issue began.I have done it in safe mode and the registry editor: https://www.youtube.com/watch?v=jAJpPCJYagI and my user folder is TEMP.

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?
