Windows 10: Switched from a Microsoft, to a Local Account, now my User Account is in a strange...

Apologies in advance for this lengthy post that probably could have been cut in half. I simply switched from my Microsoft old username Tyler Admin Account, to a Local Admin User account LunaNova. It brings up the window for you to choose a local or admin account and name, password. I gave it the new name and chose Admin user. After successfully finishing this simple process. I restart PC. I'm looking at the folder tree in File Explorer glancing through and to the Users folder and notice my name is still the previous name. I go back to check my name in User Accounts and it

Strange Windows 10 User Account issue.

Unfortunately I had done those steps numerous reboots, it just, reappears for no good reason. The base account isn't even a Microsoft account, it's a local account.

I haven't quite tried the built in administrator account on W10, but so far in my experience on my own computer, the built in account seemed to have absolutely no more control than I did on my own.

It's just strange, I go in, it warns me twice about deleting the account, then it's gone. Reboot, and it's back?

EDIT: Just to specify, both command line and Netplwiz both say only HIS account exists on the computer, it doesn't list this rogue account. This is what I meant in my first post about the fact that even Windows doesn't seem to believe it exists, HALF the time. *Frown

 

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.
