Because I have no free time to update these patch for a few months, so I plan to open the source code of the "Universal Theme Patcher".
The source code includes a console program for demo the patch engine.
You can migrate it to your own project freely.
In your final tool, add a link to deepxw is recommended. Source code link:

Vize are well-known 3rd party theme of Windows. It will try to use this patch engine.
