Windows 7: How to Reset the Thumbnail Cache

If the thumbnail pictures are not displaying correctly, resetting the thumbnail cache will fix this (most of the time). Resetting the cache will clear it and force the automatic creation of the thumbnails as needed.

1. Click the Orb (Start Button).

2. Select All Programs.

3. Select Accessories.

4. Select System Tools.

5. Select Disk Cleanup.

7. Select your Boot drive and click OK.

8. Check the Thumbnails checkbox (make sure nothing else is checked).

9. Click OK.

10. When prompted, click the Delete Files button.

    Check your folder options, there’s a check box to force displaying icon or thumbnails. Something changed mine and when I unchecked it, viola, thumbnails displayed.

    good luck.

      Thanks. This totally worked. I actually prefer Picture Manager in Windows over IPhoto. Picture Manager is so much simpler. So I did what you suggested. I went into Tools – Folder Options – View : and unchecked “always show icons, never thumbnails”(I’m not why this option exists. What’s the logic behind it?) and “display file icon on thumbnail.” Voila, unchecking these items did the trick.

    Tried all the above and did not work.
    The I chose ‘Organise’ from the pulldown menu in Windows explorer while I had a specific folder open with images that should show thumbnails but didn’t.
    The I chose ‘Folder and search options..’ and then the tab ‘display’(second from the left) At the bottom of that window I chose ‘reset default settings’ and then ‘OK’
    My thumbnails are back, but I still don’t know what option did the trick!

      Or you can do the reg trick open registry (Start – Type regedit ) go to HKEY CLASSES ROOT then to .avi export .avi to desktop name it anything and copy paste the below replacing its content

      Windows Registry Editor Version 5.00

      [HKEY_CLASSES_ROOT\.avi]
      @=”VLC.avi”
      “Content Type”=”video/avi”
      “DivX.backup”=”VLC.avi”
      “PerceivedType”=”video”
      “QuickTime.bak”=”VLC.avi”
      “VLC.backup”=”QuickTime.avi”

      [HKEY_CLASSES_ROOT\.avi\OpenWithProgIds]
      “WMP11.AssocFile.avi”=hex(0):
      “QuickTime.avi”=hex(0):

      [HKEY_CLASSES_ROOT\.avi\ShellEx]

      [HKEY_CLASSES_ROOT\.avi\ShellEx\{BB2E617C-0920-11D1-9A0B-00C04FC2D6C1}]
      @=”{9DBD2C50-62AD-11D0-B806-00C04FD706EC}”

      [HKEY_CLASSES_ROOT\.avi\ShellEx\{e357fccd-a995-4576-b01f-234630154e96}]
      @=”{9DBD2C50-62AD-11D0-B806-00C04FD706EC}”

      save it and double click (After changing the pgm with regedit)

    Hi,

    None of these solutions seem to be working for me. I have a large collection of mp3s which I spent a long time re-tagging and filing. The artwork has been manually added using Mp3tag in v2.3 format. Thumbails were displaying correctly in folders, previews and in Windows Media Player.

    Now, suddenly, no thumbnails are displaying in folders (although they continue to display in WMP). The artwork is still embedded since the folder preview still displays, just not the thumbail.

    This doesn’t seem to be something I can easily fix with display options. Does anyone have any ideas!?

    Thanks,

    Dan

    If you don’t mind doing this on a one-off basis, right-click on the thumbnail and select “Rotate clockwise” and/or “Rotate counterclockwise”. (These options only display on thumbnail images.)

    Alternatively, at the top right of the folder where you select your view type, select “small icons” then “medium icons” then “large icons”, and then whichever icon size you prefer.

    I still can’t get Windows 7 to properly display preview pics of folder contents. It used to work fine, but it just shows a blank folder icon no matter what I do. It’s very frustrating. Making me wish I still had Windows XP.

    All of the files on my desktop have become blank after permanently deleting the thumbnails. Is there a way to reverse this process to restore my thumbnails?

    That box is NOT checked but it is still displaying the photo viewing program icon rather than the thumbnail. When I change the view from med to large, for example, they resize as thumbnails but then quickly become icons again. This happened as soon as I downloaded Picasa. But I went back in tonight & under Configure Photo Viewer, I clicked “Don’t use Picasa Photo Viewer.” This didn’t bring back the thumbnails though…
