Edit authui.dll to add custom domain frame

I've been trying for some time to add my custom UI frame to domain login screen. I am hoping that someone out there can help.

I want to add the kitty cat user image to the frame. It's just the normal user image that came with windows.

I have ownership of authui.dll.
I grab the image with Resource Hacker.
I edited the file with GIMP to include the kitty cat.
I put the edited image back into the DLL and replace it in System32 and log off.
All I ever get is a black screen with a cursor.

I have a copy of the authui.dll that the user Danny on this forum create here. It actually works so I know editing it is possible. I was hoping, however, that someone could tell me what I'm doing wrong. Or just fix it.

I tried adding in a new bitmap with my edited one and was going to change the code to call the new bitmap instead of 12223 but Resource Hacker wont allow me to add a new bitmap. It's always empty when I try.

Please help me as this is driving me nuts!

Welcome to the Seven Forums

The authui.dll is in both C:\Windows\System32 and C:\Windows\SysWOW64 after you have edited both then you need to restart your computer not log off.

Even if you change the frame with your image you will not see the Kitty it will show up when you change your user account image from the Control Panel.

I guess I have never seen the Domain login screen.

I just tried with Restorator 2007(probably the best program for editing system files out there but it is not free) using your image and it states that your bitmap is corrupt so that could be your problem.

OK I have seen the domain login.

Post the kitty picture here and I will try it in photoshop and if it works I will post the .dll for you.

I'll see what I can do and get back with you later.

Here you go, I tested it and it works fine. I also used gimp instead of Photoshop for better transparency.
