Windows 10: Link a local account on a new PC to an an existing Microsoft account

Hi,On my current/old Win 10 PC I use a Microsoft account with a user ID that has more than five characters.I now have a new PC and want to add my existing MS account into this PC.On my new PC, when I created the same user ID of more than five characters, it truncated it to the first five characters :- To resolve this situation, on the my new PC can I create a LOCAL user with the user ID of more than five characters and then use the option 'Sign in with Microsoft Account instead" to link that Local account to my existing Micrsoft account with same email address ?I have seen other suggestio

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.

Hi,

Thank you for posting your response in Microsoft Community.

I understand your concern, and we in Community will try to help you in the best possible way we can.

I suggest that you follow the steps below and check if you can log into your computer using the Local Account.

• • On the Search Bar type “User Account”.
  • On the right menu pane locate and click “Make changes to my account in this PC”.
  • Then locate and click on “Sign in With a Local Account instead”.
  • And follow on screen instructions.

Hope this information is helpful.

 

Change Microsoft Account Details in Administrator Account


Hi Daryl, welcome to the Ten Forums.

It's quite easy in fact, simply switch the account in question first to a local account, then switch back to a Microsoft account, this time using your wife's MS account credentials.

• Step 2: Microsoft Account - Switch to in Windows 10 - Windows 10 Forums

Notice that before doing this you need to remove the new additional MS account on the PC, the one you created with her credentials. Windows allows only one user account for each email address, if the new account exists you cannot switch the original administrator account to an MS account using the same email address.
