Windows 10: What is "UPN?"

"UPN" appears in my Program files across my 4 laptops. From reading, it appears to be a MS thing.

What is it for? If nothing in particular, how do you remove as does not appear in, "Uninstall Programs."

I searched back to 2016 for explanation for UPN, and nothing. I stopped at that point.


My laptops are for home use only. I have WIN 10, 1909

Should Hybrid joined computers allow login with UPN first

Hi, I'm looking to understand if hybrid domain joined computers should be able to logon with the users UPN in the first instance when no direct line of site to an on premises domain controller.

We have examples at our organisation where a user is permanently based offsite and we wish to send them a brand new computer that they have not logged onto before. Currently we either ask them to come collect the computer and log onto it before taking it
away or we set them up with a local account (really want to move away from this option).

We have implemented hybrid domain joined computers as we cannot move away from group policy at this stage but none of our hybrid domain joined computers allow UPN login when no line of site to a domain controller. Is this normal behaviour?

Note: UPN logon does work if line of site to a domain controller and with locally cached username.

 

We can't sign you in with this credential because your domain isn't available.

I am getting this error message while changing password of my domain account. I have alternate UPN suffixes in my AD DS, i.e. contoso.com.np as Primary domain name and contoso.com as alternate UPN suffix. Please suggest the solution for this error.

 

Change Security Device Credentials

I have a AAD joined Windows 10 device (Surface Book 2). Recently, my UPN changed, however, the "Security Device Credential" still has my old UPN, and doesn't work to connect to resources. How do I change the Security Device Credential to reflect the
changed UPN?
