Follow these steps to configure the theme settings for Windows:

Registry Key Modification

To modify the theme settings, you will need to make changes to the Windows registry:

1. Modify HKEY_LOCAL_MACHINE Registry Key

  1. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes.
  2. Create a new directory under Themes called Personalize.
  3. Add a new DWORD (32-bit) value named AppUseLightTheme.
  4. Set the value of AppUseLightTheme to 0 (zero).

2. Modify HKEY_CURRENT_USER Registry Key

  1. Navigate to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes.
  2. If the Personalize directory is present, open it.
  3. Change the value of the DWORD AppUseLightTheme to 0 (zero). By default, this value will already be set to zero.

Note: Modifying the registry can affect your system's behavior. Ensure that you back up the registry before making any changes.
