    Explorer not showing thumbnails.


    Recently I noticed Windows 10 Explorer was becoming very slow.

    I followed some online advice to try and rectify this stupid of me - should have come here first. Now many thumbnails are not showing in Explorer.

    I would really appreciate any help.

    :)

    File Explorer not showing thumbnails

    Brink,

    Many thanks for you reply. I have done all the steps you suggested, but no change,

    When I open a folder containing photos, some open correctly but the vast majority open with thumbnails, but they very quickly get overwritten and you can not longer see the thumbnails.

    Are there any more suggestions?

    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.

    Explorer not showing thumbnails.

    File Explorer - Some PDF's show thumbnail image, some don’t

    In Windows 10 File Explorer, I see thumbnails for a few of my pdf files but still see the generic Adobe pdf icon for most of them.

    • In Windows 10 folder options, the checkbox for “Always show icons, never thumbnails” is unchecked.
    • On the Adobe Reader preferences general tab, “Enable PDF thumbnails previews in Windows Explorer” is checked.
    • Adobe Acrobat is set as my default PDF viewer.
    • I have used Disk Cleanup to delete all my thumbnails to clear and rebuild the cache, yet the problem persists.
    Any suggestions on how I can see all the pdf icons as thumbnails?
    Windows 10 Pro, Version 1903, Build 18362.657
    Adobe Acrobat Reader DC (20.006.20034)

    I asked over in the Adobe Acrobat Reader forum a few days ago but have received no replies.
