PS: A program called FastPictureViewer supports animated gifs in the photo viewer, but you can only 'view individual frames within animated GIFs'. or did Microsoft seriously not get around to adding the support themselves? To browse photos within a folder, open a photo from the Folders view or File Explorer, then swipe right or use the arrow keys to see the next. Change mouse wheel settings in More > Settings. Press Ctrl + the mouse wheel to zoom in or out. The Photos app in Windows 10 does the same things Photo Viewer did, and more.

So, what I'm asking is, is the reason the photo viewer doesn't support animated gifs is because of the fact that WIC only supports still images? Or is it that WPV doesn't have supported coded in for animated formats but WIC codecs can support them? If it's either of these reasons, I guess I have no reason to start this project (creating a WIC codec for animated GIFs). If Windows Photo Viewer isnt in the list, you cannot install it on Windows 10. I'm guessing this means I could make a replacement GIF codec to replace the built-in one, but before I do I need to know something. But since the photo viewer uses WIC ( Windows Imaging Component) to decode images, this system can be used to add support for just about any format. People have suggested various third-party software (AKA not the built-in windows photo viewer) to solve this shortcoming. I've been doing a bit of research to find out why Windows 7 won't support animated GIF images in the photo viewer natively.
