MajorGeeks Wallpaper is the background wallpaper we use, as seen in many tutorials, YouTube videos, and more.
We decided to share this after being asked a few times by some of our readers. It was never designed for sharing but was originally designed for t-shirts and other swag.
That said, it works well, especially for dark themes. There is a single 2700 X 2700 PNG image. Extract the image from the ZIP file. Right-click and click on 'Set as Desktop background.'
Uxtheme Multi-patcher will allow you to use any 3rd party msstyle theme on Windows (with Themes enabled) just by patching the uxtheme.dll (dynamic link library).
