Windows 10: Locked out of computer because user switched automatically from local to Microsoft account.

Hi,I have always used a local user on my Windows 10 laptop and logged in with the local password. However, a few days ago, the user was automatically switched from a local user to a Microsoft account user of a Microsoft account I have never used and can't login to. I believe this happened after I held down the power button to restart the computer.Now I can't login, because I don't know the password, PIN or which of those is even set for the Microsoft account. I probably only created the account when I first got the computer because Microsoft prompted me to. I have also not been able to reset t

Switch Back to Existing Local Account from Microsoft Account

I already identified that I had tried this, and that it did not allow me to switch back to the original Local Account. The Microsoft Account hijacked the User Name of the original Local Account. When I click "Sign in With a Local Account instead" and enter
the original User Name, Windows 10 won't proceed. The only way to get back to a Local Account is enter a new User Name.

 

Local Acct user and MS account user - sync them or merge them

If the local account is the one where you have most of your personal data, this is how I would do it:

• Sign in to your Microsoft account
  
• Copy all documents, pictures and other personal data from Microsoft account's user folders to corresponding folders in user Public (contents of MS account Documents folder to Public Documents folder and so on)
• Sign out from Microsoft account

Notice that above steps are only required if Microsoft account user folders contain data you want to keep. If its user folders are empty or do not contain anything worth saving, you can skip the above steps. Continue from below.

• Sign in to the local account
  
• Delete the Microsoft account (Option One in this tutorial)
• Switch your local account to a Microsoft account (tutorial)
• Copy the data backed up from old Microsoft account to Public folders to new Microsoft account in corresponding folders

That's it. Using the Public folders as temporary storage you will have none whatsoever file owner / permission issues later on.
