Windows 10: Change Windows' username associated with a Microsoft account

Hello,

I have some trouble to solve a misspelled username in Windows 10.

I am referring to the username used for the user's home folder.
This username seems to be recorded somewhere in your Microsoft account but I am not able to find a way to edit it. It is automatically used when you install a new Windows machine, avoiding so to ask you for a username.

I asked this issue to the Microsoft support but their "solution" instead of solving the problem it just broked the system and I had to revert changes in rescue mode to make it work again...

If there is a solution, I hope this post will help to highlight it,
Thanks in advance.

:)

Hi

Are you logged in with the Microsoft account or a local account?

You can follow the steps below to change the username and check if it helps.

• Press Windows key + X key.
• Click on Control Panel.
• Under view, select large icons.
• Go to User Account.
• Click on Manage another account.
• Select the User Account for which you want to select the password.
• Click on Change the username.
• Click on Change Name button.

Hope this information is helpful.

 

How to change the Windows 10 truncated local account username without losing all the associated account information?

When Windows 10 creates the local user, it uses the first 5 characters of the Microsoft Account's email address.

It also uses it to name the directory where the users information is kept.

If the Microsoft Account email address is myusername@gmail.com ...

then the local account username will be myuse

and the directory path will be ...

C:\users\myuse

This is bad for many reasons we can discuss later.

The problem is that there is no one at Microsoft Support that understands the issue.

There are hundreds of posts here and elsewhere on the net about this.

Below I pasted one suggestion from a Microsoft Support Engineer.

It is wrong.

One can only "Change the account type" in Control Panel using this method.

It cannot "rename the local user account."

Even if you create another administrator user the option to Change the account name

is not available if that user has a Microsoft Account.

So my question: is there a way to correctly change the truncated local username from myuse to myusername without
losing all the associated Microsoft Account information?

I have seen many convoluted solutions on the net.

Please... NO guessing and NO "point-and-click-and-pray" solutions.

Just an honest discussion from Microsoft or the community.

Thank you,

Robert Lorbeer
