Windows 10: Photos App - No Thumbnails

On my neighbour's machine (that I did a clean install on) when they load pictures from their camera, and the Photo app launches, all the photos/pictures shown in the Photo app are blank - i.e. the thumbnails are not showing. On this machine thumbnails are set to show and if you look at, for example, the Pictures folders all pictures are shown as thumbnails (via explorer). The set up of this machine is the same as mine and on my pc the Photo app icons do show as thumbnails. I have been trying to turn my Photo app thumbnail preview on and off but do not know how to do it. My logic being of I can turn thumbnails on and off in the Photo app I could get to the route of my neighbour's problem.

Solved

The photos are not cached, just the thumbnail is cached. The thumbnail must be stored in the app data if they are still there after you remove and reinstall the app.

 

After Windows Update all Photos Icons Can Only be with Photo App Insignia

Uncheck "Always show Icons, never Thumbnails" You said " now all of my photos, in thumbnail form, show only the Microsoft Office Photo App insignia." But if you changed the Default to Windows Photo app, are you still seeing the "Office Photo App insignia?"
