Windows 10: Combining existing microsoft account with new one

I must have had another Microsoft account prior to the new one that I created because it is saying that my email is already in use.

How do I combine accounts and/or delete old account?

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.

Tutorials:

• Step 1: Local Account - Switch to in Windows 10 - Windows 10 Forums
• 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.

Hi Hitendra,

Thank you for posting in Microsoft Community. I understand your concern and I am glad to assist you.

I would suggest you to switch your Microsoft account to a Local account first and then switch back with a new Microsoft account. Please refer to the following steps:

Step 1:

• Type Manage your accounts
  in the search bar and click on it
• Click on "sign in with a local account instead"
• Press next and complete the process.
• If you do not have a local account, leave the credentials blank and proceed.

Step 2: Now, on the newly converted Local account, follow these steps to add a new MSA.

1. In the Start search, type "Manage your accounts" and press Enter.

2. Choose 'Accounts'.

3. Click on "sign in with a local account instead"

4. Enter the Microsoft account ID and Password and click Next.

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
