Thank you! The dark webp display in Windows Photo viewer has been irritating me for a long time. The instructions worked perfectly, and now images appear as they should.

Brilliant! Many, many thanks. Worked in Windows 10 (20H), enabling continuous scrolling through image folder using Windows Photo Viewer.
