    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.

    Preview and thumbnails are not showing up in Windows Explorer, Adobe Acrobat X Pro.

    Hi Susanne,



    Thank you for writing to Microsoft Community Forums.



    We understand your concern. The PDF Shell component in Adobe Reader allows you to see the thumbnails of PDF documents in Windows explorer. However, it seems Preview and Thumbnails of PDF files are disabled. Please follow steps mentioned below to enable
    the same.



    1. Launch Adobe Reader.
    2. Click on Edit in the menu bar and choose
      Preferences.
    3. Highlight General under Categories.
    4. Check the box behind Enable PDF thumbnail previews in Windows Explorer.

    You may also want to refer
    Enable thumbnail of PDFs in Windows Explorer     for more details.
