CLH_GINA

• Fork of ConsoleLogonHook that uses resources from msgina.dll from Windows NT 4.0, 2000, or XP to create a GINA-like logon screen.

Warning

THIS PROJECT IS IN EARLY DEVELOPMENT AND MIGHT BE UNSTABLE

You may encounter issues using a Microsoft account, however, this will work perfectly fine on local accounts.

Disabling the lockscreen and the CTRL Alt Del logon keybinds is recommended as they're not fully implemented yet.

Knowing this, You might use this at your own risk.

3. Enjoy.

Installation

Warning

This will require administrator privileges to be installed.

• If you have installed the original ConsoleLogonHook, replace ConsoleLogonHook.dll and ConsoleLogonUI.dll with DLLs from this repository and proceed to step 4.

1. Copy the 2 DLL files (ConsoleLogonHook.dll and ConsoleLogonUI.dll) from Releases into %SYSTEMROOT%\System32

2. Open a CMD window as TrustedInstaller via PsExec64 and copy and paste the following commands:

reg add HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsRuntime\ActivatableClassId\Windows.Internal.UI.Logon.Controller.ConsoleBlockedShutdownResolver /v DllPath /t REG_SZ /d %systemroot%\System32\ConsoleLogonHook.dll /f

reg add HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsRuntime\ActivatableClassId\Windows.Internal.UI.Logon.Controller.ConsoleLockScreen /v DllPath /t REG_SZ /d %systemroot%\System32\ConsoleLogonHook.dll /f

reg add HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsRuntime\ActivatableClassId\Windows.Internal.UI.Logon.Controller.ConsoleLogonUX /v DllPath /t REG_SZ /d %systemroot%\System32\ConsoleLogonHook.dll /f

reg add HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsRuntime\ActivatableClassId\Windows.Internal.Shell.PlatformExtensions.ConsoleCredUX /v DllPath /t REG_SZ /d %systemroot%\System32\ConsoleLogonHook.dll /f

or merge the regkey in the release zip as trusted installer.

3. Take ownership of the file Windows.UI.Logon.dll and rename it to something else. Example: Windows.UI.Logon.dll.bak, this is required as it will force the use of the console logon screen.

4. Get a copy of msgina.dll from Windows NT 4.0, 2000, or XP and place it in %SYSTEMROOT%\System32.

Registry keys

General Windows logon screen customization

• (RECOMMENDED) Disable the lockscreen
  • Create a DWORD value named NoLockScreen in HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization and set it to 1.
• To manually type the username, create a DWORD value named DontDisplayLastUserName in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System and set it to 1.`
  • This is optional, as CLH_GINA handles the friendly logon as well.
• To enable verbose logon messages, create a DWORD value named VerboseStatus in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System and set it to 1.

Customizing the pre-logon background and color scheme

• Color scheme: HKEY_USERS\S-1-5-18\Control Panel\Colors.
  • It is recommend to run WinClassicThemeConfig as NT AUTHORITY\SYSTEM with PsExec or gsudo to change the color scheme of the logon screen.
  • Or set CustomWallHost to the path of the WinClassicThemeConfig executable temporarily and go to the switch user screen to change the color scheme and window metrics.
  • Make sure to remove the CustomWallHost value after changing the color scheme, as it is possible to spawn a SYSTEM cmd.exe with WinClassicThemeConfig through file dialogs.
• To prevent reverting to the default color scheme, rename HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\DefaultColors\Standard to something else.
• Background color: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Background, default is 0 0 0 (black). Delete the value to use the background color from the color scheme.
• Background image: HKEY_USERS\S-1-5-18\Control Panel\Desktop\Wallpaper. (REG_SZ, create if missing)
• Background image style: HKEY_USERS\S-1-5-18\Control Panel\Desktop\WallpaperStyle, default is 0 (centered). Set to 2 for stretched, 6 for fit, and 10 for fill. (REG_SZ too, create if missing)
• Set HKEY_USERS\S-1-5-18\Control Panel\Desktop\TileWallpaper to 1 to tile the background image.
