Disables visual styles, effectively enabling the Windows Classic theme. This mod uses the method of closing access to the memory area where the theme is located. It is one of the multiple methods of enabling Windows Classic theme.

The mod injects only in the process Winlogon.exe, and exits once the handle of the memory area is closed. It does not hook any functions.

The mod affects only programs started after enabling the mod.

The following additional steps are strongly recommended:

1. Windows Classic theme is not compatible with Windows 10 Task Manager. Before enabling the mode, install the classic task manager.

2. Rename this registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\DefaultColors\Standard to prevent the color scheme change after pressing Ctrl+Alt+Del or going to the logon screen and back.

3. If you want the 3D borders in menus, import the following reg file:

   Windows Registry Editor Version 5.00
   [HKEY_CURRENT_USER\Control Panel\Desktop]
   "UserPreferencesMask"=hex:9E,1E,05,80,12,01,00,00
   

4. Windows Classic theme is not compatible with Windows 11 taskbar. On Windows 11 version 21H2 to 23H2 it is recommended to enable the Windows 10 taskbar with the Windows 10 taskbar on Windows 11 mod while on Windows 11 24H2 install the Windows 10 taskbar using the Win10 taskbar on Win11 24H2 mod.

5. The Windows 10 taskbar still needs a compatibility fix, so install the mod Classic Theme Explorer Lite.

6. If you are using the Windows 10 taskbar, install the OpenShell utility. After installing the OpenShell, put the patched file StartMenuDLL for OpenShell 4.4.190 into the Open Shell folder, replacing the existing one. Alternatively, install the patched version of OpenShell4.4.191

   Alternatively to patching OpenShell you can install the mod Classic Taskbar background fix, but read carefully the instructions there. The mod way will still leave vasual glitches when the task buttons are dragged, so the patched Open Shell way is recommended.

   After installation, import the following REG file with OpenShell settings:

   Windows Registry Editor Version 5.00
   [HKEY_CURRENT_USER\Software\OpenShell\StartMenu\Settings]
   "StartButtonType"="ClasicButton"
   "CustomTaskbar"=dword:00000001
   "TaskbarLook"="Opaque"
   "TaskbarColor"=dword:00000000
   "SkinC1"="Classic skin"
   "SkinOptionsC1"=hex(7):43,00,41,00,50,00,54,00,49,00,4f,00,4e,00,3d,00,30,00,\
   00,00,55,00,53,00,45,00,52,00,5f,00,49,00,4d,00,41,00,47,00,45,00,3d,00,30,\
   00,00,00,55,00,53,00,45,00,52,00,5f,00,4e,00,41,00,4d,00,45,00,3d,00,30,00,\
   00,00,43,00,45,00,4e,00,54,00,45,00,52,00,5f,00,4e,00,41,00,4d,00,45,00,3d,\

   53,00,3d,00,30,00,00,00,54,00,48,00,49,00,43,00,4b,00,5f,00,42,00,4f,00,52,\
   00,44,00,45,00,52,00,3d,00,31,00,00,00,53,00,4f,00,4c,00,49,00,44,00,5f,00,\
   53,00,45,00,4c,00,45,00,43,00,54,00,49,00,4f,00,4e,00,3d,00,31,00,00,00,00,\
   00
   
   [HKEY_CURRENT_USER\Software\OpenShell\ClassicExplorer\Settings]
   "StatusBarFont"=""
   "ShowStatusBar"=dword:00000001
   "UseBigButtons"=dword:00000000
   "TreeItemSpacing"=dword:fffffffe
   "NoFadeButtons"=dword:00000001
   "FullIndent"=dword:00000001
   
   [HKEY_CURRENT_USER\Software\OpenShell\StartMenu\Settings]
   "StartButtonIcon"="%SystemRoot%\\System32\\slui.exe, 2"
