Microsoft account in Win 10, remove and replace with another existing microsoft account

Hi. I'm Brian and I will do my best to help you.

If this had been me, I would have converted the existing account to a local account and then reconverted to a Microsoft account using her credentials.

My name is Mayumi. I'm an Independent Advisor and I'll be glad to help you today.

I understand that you want to remove your primary Microsoft account from your wife’s computer and make your wife’s Microsoft account the primary one.

To do so, you will need to CREATE a New Local Administrator account,

transfer all data from your wife’s account to the new account, and then remove your Microsoft account from the computer.

Here are the steps:

1. Create a new local administrator account by following these steps:

   - Press Windows key + I to open Settings.
   
   - Click on Accounts.
   
   - Click on Family & other users.
   
   - Click on Add someone else to this PC.
   
   - Select I don’t have this person’s sign-in information.
   
   - Select Add a user without a Microsoft account.
   
   - Enter a username and password for the new account and click on Next.
   
   - Click on the newly created user and select Change account type.
   
   - Set the account type to Administrator and click on OK.
   

2. Transfer all data from your wife’s account to the new account by following these steps:

   - Log in to the new local administrator account.
   
   - Press Windows key + R to open the Run dialog box.
   
   - Type control in the Open field and press Enter.
   
   - Click on User Accounts.
   
   - Click on Manage another account.
   
   - Select your wife’s Microsoft account and click on Change the account type.
   
   - Set the account type to Administrator and click on OK.
   
   - Log out of the new local administrator account and log in to your wife’s 
   
     Microsoft account.
   
   - Press Windows key + R to open the Run dialog box.
   
   - Type %userprofile% in the Open field and press Enter.
   
   - Copy all files and folders from this location to a safe location (such as an 
   
    external hard drive).
   
   - Log out of your wife’s Microsoft account.
   

3. Remove your Microsoft account from the computer by following these steps:

   - Log in to the new local administrator account.
   
   - Press Windows key + I to open Settings.
   
   - Click on Accounts.
   
   - Click on your Microsoft account and select Remove.
   
   - Follow the prompts to remove your Microsoft account.
   

After completing these steps, your wife’s Microsoft account will be set as the primary one, and all her data, shortcuts, passwords, etc., will be preserved.
