I recently had to re-install my Vista and got updates from i430vx.net, but obviously it didn't update Windows Photo Gallery!
When I start slideshow, the picture is pixelated and there is a control bar on the bottom. I don't remember it to be that way when I had my updates automatically installed from Microsoft servers before Aug. 2020. All that makes me think I have a really old version of WPG. I also don't know how to check the version, and when I try to check for updates, it tells me that I have the latest version.
