Why domain joined Windows does not change user name after name change on AD login ID?

Question

Why domain joined Windows does not change user name after name change on AD login ID?
Here is the scenario:

A user had a name change in an active directory account. Machine is domain joined. They're able to sign into computer using their domain account, but sign in screen and user profile folder in c:\users do not reflect new name. Especially, user does not want an old last name to show up on windows sign in screen?

Thoughts:

I was under the impression windows will create user profile folder automatically when logging with new login ID which was renamed, but that did not happen.

Would removing the machine from domain and rejoining fix the issue?

Hi,

Changing the username(samaccountname) doesn't change the profile name in windows. Since the SID is the same. the profile will automatically mapped with the new login authentication without any changes to the profile.

you need to manually update the profiles. Like take backup and rename/delete the existing profile and let AD login create new one. Then copy the backed up data.

ensure the profile path is not depended on application installation or any other components.
