Disabling the Windows Welcome screen after sign-in about windows-credential-provider-library HOT 2 OPEN

Hi @DavidWeiss2! I'm trying to make another project, and was hoping you could help me out or point me in the right direction. I'm trying to fully disable the welcome screen when Windows boots and a user is automatically signed in. The intent is to "consolize" Windows as much as possible and have it boot straight to a game UI like Steam Big Picture.

Do you know how I could completely disable it, put a black photo on top of all the welcome UI elements so the screen appears black?

Unfortunately neither of those are applicable. I'm referring to this screen that appears when the user is automatically logged on. So not the sign in screen which appears directly after the the windows logo, but the UI with the spinning wheel, username of the user being signed in and their profile photo.

The Windows kiosk single app would prevent the usage of the desktop after Steam or Playnite has launched, which would defeat the purpose. The Windows "Custom Logon" feature does exactly what I want, and I can confirm it does work on Windows 10.

However, Custom Logon does not work on 11 from my testing. I've tried it on 11 Pro, 11 Pro Education, and 11 Workstation. I'm trying to replicate that functionality, either by disabling the Welcome screen entirely, finding a way to display a black image over all of the welcome screen UI elements, or re-enabling the Custom Logon feature to function on Windows 11.

Can one of your credential provider examples be used to solve this?
