Changing Windows Logon screen Avatar

Desktop PC Running Windows 11 Pro version 25H2

I have this workstation configured on a Windows 2022 domain. It all seems to be working fine.

I have the logon screen set so that if I lock the machine the logon screen shows the field to enter the user password to unlock the system. The logon screen also shows the Avatar image photo of the user logged in. The user Avatar images are stored in Active Directory using the Application from CodeTwo - Active Directory Photos.

This all functions as expected.

What I cannot resolve is the following:

I want to replace the Avatar image on the logon screen that is displayed for the initial logon to the system. I want to replace the standard Microsoft simple user Avatar image used on the logon screen but only for the initial logon to the system when there is currently NO user actually Logged In.

At this point the logon screen displays the standard user Avatar Image wit the words with the words "Other user" under the image. Followed by the two fields to enter the username and password. Below them is text which shows the domain name to sign into. followed by a message "How do I sign into another domain"

It is the Avatar image on this screen that I want to change to the company Logo.

I have tried creating new image files in the C:\ProgramData\Microsoft \User Account Pictures Replacing the image files for the standard windows image files. However I cannot get this to work. I have tried changing the settings in both the group policy and vis the registry to set all logons to use the same image files. This actually works to force the logon screen when No user is logged to display the correct Avatar image of the company logo but the negative effect is that it overrides the users Avatar image that is displayed on the logon screen when they lock there logged in session.

I hope someone can throw some light on this and point me in the right direction.

When I say Company Logo. This system is for a local charity that I support. Which is part of the "Men-In-Sheds Organisation"

please try
settings > accounts > your info

within that window
adjust your photo > browse files

it should show that picture on your log on screen for that account.

Hi Steve, thank you for your reply. I will get a windows 11 pro machine that is not connected to a domain and carry out some testing to see if there are any any differences between a standalone machine and a domain connected machine. But the issue I am trying to get around is if no user is currently logged on then I want to change the default avatar image that appears on the initial logon screen when there is no current user logged on. From what I can see there is two variations of the way the logon screen functions the first is where there is no user logged on and the logon screen requires the username and password fields to be filled in and the logon page uses a default avatar image the second use of the logon screen is where their is a user currently logged on and the lock screen has been activated due to no activity by the user causing the pc to be secured and locked and the lock screen to be called. However when activating unlock. The screen changes from the lock screen to the log back in screen this now correctly displays the avatar of the currently logged in user with the correct avatar image for that user. Also on this screen is text showing the name of the user currently logged on and a single field requiring only the current logged in user password. Should probably point out that I do not have fast user switching enabled so I only ever have one user at a time allowed to have an open session on this workstation. So the only two scenarios exist either there is no user logged on the machine or there is currently a user logged in and the session has been locked.
Please accept my thanks for your prompt response.

i have found this

also i found this

but also if you go to your online MS account you can change the default picture there
to one of your choosing which would also show on log on
if you are connected to that on line account for that log on.

best of luck Steve ..

@garlin breaks it down here too

I don't have an AD setup for testing, but here's my experiences working with user account images:

If you don't assign a personal image to each account (based on their SID), then Windows defaults to the generic user icon. After you correctly assign the images in all the required resolutions, it shows up on the Logon/Lock screen, the Taskbar and Settings.

If you don't complete the mapping in all the sizes (up to 1080 pixels, then it's missing in a few places like Settings).

On a shared PC, the Logon screen will display the icon of the last logged on user. To prevent that, you use the GPO setting to hide the last user's profile. Now you get the generic "Other User", which is a placeholder.

The generic icon is saved as the "\ProgramData\Microsoft\User Account Pictures" version of user.bmp image in all its different sizes. You would overwrite user-*.png (not the original BMP file, since it's the backup copy of the generic icon).

This should be the icon displayed when no last user is shown, because there are no other generic icons outside of this folder.
