Fix: Thumbnail Previews Not Showing up in File Explorer

Are your image files showing up with a generic mountain and lake scene instead of the miniature or thumbnail display in File Explorer? And video files may show up with the default media player icon.

This article tells you how to enable thumbnail preview and the preview handlers in File Explorer on Windows 10 and earlier.

Fix: Thumbnails Previews Not Showing up in File Explorer

To view the thumbnails for your images, media or other file types, choose one of the following folder views from the ribbon toolbar:

  • Medium Icons
  • Large Icons
  • Extra Large Icons

If thumbnail previews are not still not displayed, follow the steps below.

Enable thumbnails via Folder Options

  1. From the File menu, click Options. This opens the Folder Options dialog.
  2. In the View tab of Folder Options, uncheck the following option:
    Always show icons, never thumbnails
  3. Click OK.

    Alternately, you can also enable thumbnails via the Performance Options dialog.

    Launch sysdm.cpl via the Run dialog → click Advanced tab → Performance → Settings → Show thumbnails instead of icons → OK

This restores the thumbnail images for your pictures, media, and all other file types.

[Tweak] Enable or disable thumbnail view via the right-click menu

To toggle the display of thumbnail previews without going into Folder Options every time, here is a Windows Script solution for you that adds the Enable/Disable Thumbnails in the right-click menu.

  1. Download togglethumbs.zip and save it to the Desktop. The archive contains a registry file and a VBScript — both are plain-text files.
  2. Unzip the archive and extract the contents to a folder.
  3. Move the file togglethumbs.vbs to the C:\Windows directory.
  4. Double-click togglethumbs.reg to merge the contents to the registry.

The Enable/Disable Thumbnails option is now added to the context menu, which will be seen when you right-click on the Desktop and when right-clicking on an empty area in a folder.

This adds the Enable/Disable Thumbnails option to the right-click menu. This script works in Windows Vista, 7, 8 and 10.

Clear the thumbnail cache

If the thumbnails still don’t show up in File Explorer, see if clearing the thumbnail cache using Disk Cleanup helps.

Thumbnails missing in OneDrive folders?

In some systems, the thumbnail previews don’t show up in the OneDrive Documents or Pictures folders, even though the files are available offline.

To workaround the problem, disable the Files On-Demand feature in OneDrive.

Launch OneDrive, open settings. On the Settings tab, disable the Save space and download files as you use them checkbox.

Preview Pane not working?

If the preview pane on the right shows the generic image instead of the actual image preview or video mini-player control, you’ll need to enable the Show preview handlers in preview pane option in Folder Options dialog.

  4. …wonderful!

    Using Classic Shell you can put an icon on menu bar to toggle it 1 click directly. ->Settings for Classic Explorer (3.6.5 or later) > Toolbar buttons> Avail. commands:> Custom commands. Just target the button to the togglethumbs.vbs on Windows directory. You can choose any icon, i.e. System32\imageres.dll, 71 or other ”pictures images”.

    If you want to install Classic Shell and disable start menu modifications:
    “On Vista and Windows 7 the classic start menu is started using the
    HKLM\Software\Microsoft\Windows\CurrentVersion\Run registry key,
    which is shared by all users.” Remove the Classic Start Menu value:
    C:\Program Files\Classic Shell\ClassicStartMenu.exe

  11. I have tried eight disk cleanups. I have performed six hard and soft reboots to the computer. I have tried deleting the cache several times. I have checked and unchecked the show thumbnails not icons and show icons not thumbnails about eighteen times. Hell, I even tried the fixes that require Command Prompt! Yet, nothing works and I am still getting generic icons for most of my files and folders!

    • I am having the same issue. I don’t see dates on any of the replies here so I have no idea when you wrote this, but since the last Windows update (I dunno, about a week ago? It’s now 10.25.2021) this problem rose and now I’ve been searching for days, literally, for a fix.

      I’ve googled my fingers off, I’ve done just about everything but dance a jig and I still do not have all my picture thumbnails showing. Desktop icons are fine. File folders in Explorer are fine. But images… mostly jpg I’ve noticed, but even some of them show. It’s bizarre and I’ve now been studying Linux to see if I wanna make the move. SOOO tired of Winblows.

      Hopefully someone will know what is going on because the dozen or so fixes I’ve tried have done nothing.

  12. I have nearly given up trying to resolve the thumbnail issue which was brought on by a Windows 10 update. Obtaining assistance from m$ is futile. Have tried many many suggestions but nothing works. Therefore, since the vbs script was something new, thought I would try it. However, there is no way for me to move, copy or cut the vbs script to the windows folder. Do you have any suggestions? Thanx!
