    File Explorer not showing thumbnails


    My file explorer is not displaying thumbnails ( as it was earlier) instead it is showing default program icon ( windows photo viewer, set as default for all pictures) for all picture files like jpgs, bmps.
    When I browse folders containing pictures. at first it displays thumbnails ( as it should ) and then immediately all thumbnails change to default icon.
    When I double click any icon, it opens in its associated program correctly.

    I have tried and checked all things commonly being referred when I have Googled my problem. .
    I have checked all the common places like organize folder -> view -> 'always show icons never thumbnails' is unchecked
    I have checked group policy settings.

    Grateful if someone could point me in the correct direction to rectify this problem!

    Many thanks,

    :)

    Windows Explorer crashes and thumbnails problem

    Hi, I hope you can help me.
    Windows Explorer is no longer showing thumbnails on files played by Windows Media Player. I've run cmd and regsvr32 shmedia.dll and regsvr32 shimgvw.dll. That seemed to solve the problem...but it created a different one. Now when I try to open a folder on an external hard drive it crashes. I read in an old 2008 post it was an avi file causing the problem and suggested the run cmd regsvr32 /u shmedia.dll. That solved the opening problem but recreated the thumbnail problem. Any help to achieve both functions would be greatly appreciated. Thank you.

    PDF thumbnails not showing in Windows 10 file explorer

    In Acrobat Reader DC, go to Preferences > General and then select Enable PDF thumbnail previews in Windows Explorer.

    This should show thumbnails in File Explorer. For some reason, my selection got turned off (not by me). Check your settings again. I have done this same step for numerous computers now, and so far they all work.

    The first time you do this, Adobe Reader DC actually has a pop-up saying something like installing a add-on or extension. If you don't see this, then I suggest a reinstall of the latest DC.

    File Explorer not showing thumbnails

    Thumbnail support for Adobe Applications within Windows Explorer

    The OP doesn't want icons, they want to see thumbnails showing an image of the document contents for all the Adobe file types listed.
