As per the thread title, the Metro Photos app in Windows 8.1 no longer works for me. When opening it, I can see the folders, but the picture files themselves aren't displayed (as if they don't exist). If I select Skydrive from the photos app, it doesn't see anything either. It also seems to have affected my Onedrive metro app, as now I can't see thumbnails of the pictures (though at least it still recognizes the presence of the pictures themselves.) I think this was caused by an app that I made the default for viewing pictures, but now that I reverted back to the default photos app, something must have broke. I can't uninstall the photos app to reinstall it. If I use Metro Commander, I can see the image thumbnails just fine within that app (this also doesn't affect pictures viewed from the desktop). Thing I have tried: Made Photos the default pictures app in settings Created a new folder for the Photos Library Restored Library to defaults Deleted indexing database and created a new one. Created a new user account to see if it works, nope Any other ideas ASIDE from performing a Windows refresh?
