When I hover over a file that is supposed to have a preview option in Windows Explorer, the preview pane in explorer is blank. If I hover over a file that doesn’t have a preview handler, it says “Preview not available” However the preview of images does work. Office files and PDFs won’t display. I have checked all of the suggested folder options and they are set correctly. I have also found the preview handlers in the registry and they are all referenced there. I tried repairing Office and also did a sfc /scannow. Is there something that I am missing?
