Windows 10: After a failed update, all my program settings are deleted, all my signed accounts are...

I have a serious issue. Today I turn on my computer and all my settings are lost. When accessing to the browser I notice a clean installation and all my accounts are closed, I had Whatsapp for desktop and now I cannot use it because all the apps managed by Microsoft Store are updating including the Microsoft Store app I cannot access either.This is a serious issue because I have no space problems 149 Gb free and the only problem I notice is one failed update today. Can this update be responsible of all this mess? It's a real pain to me to connect to all my services again and I have no idea w

[Solved] Delete "Ghost" Account?

It wont show a users folder until its been logged in

Note: When you want to delete a user account from your computer:

You must be signed in as an administrator to be able to delete a user account.

You will not be able to delete a user account that is currently signed in. You will need to sign out the user first.

Be sure to always have at least one enabled administrator account on the PC to avoid not being able to perform actions that require administrator rights.

Step 1: Steps to Remove a User Account in Settings

Press Windows key, click on Settings.

Click on Account, click on Family and other users.

Select the user you want to delete under Other users and click on Remove.

Accept the UAC (User Account Control) prompt.

Select Delete account and data if you wish to delete account and the data and follow onscreen instructions.

OR

Step 2: Steps to Delete a User Account in Command Prompt

Press Windows + X keys from the keyboard, select Command Prompt (Admin).

Type net user and hit Enter to list the user accounts on your device.

Type net user "User account " /delete and hit Enter to delete the user account.

 

Your Microsoft account needs you to sign in again-recent credentials

Yes the correct or current info is in the Settings/Accounts/Your email and accounts.
The steps in the tutorial included signing in after deleting a listing. I couldn't see where that was relevant since its a second listing. It looks like I have to voluntarily do the 'sign in' so I can avoid doing that. I'm locked out for 30 days anyway.
Perhaps its time to set up a stand alone user account in that laptop <grin> Too nerve wracking dealing with this MSAccount.

 

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?
