This tool can help you create the tile icons needed for a Windows 10 program.
It will work well if you can provide a source image that:
Turn your logo into a “silhouette”: It will become white (except for transparent areas). This matches the (old) style of Microsoft icons (Win 8 – early Win 10 era).
For realistic previews, set the color of the tile background: The generated images will still use transparency. This tool doesn’t make full-bleed icons.
