After upgrading from Windows 8.1 to 10, I noticed that.psd Photoshop files started having thumbnails again, something I've not seen since CS2.Once I tried to open a.psd, it asked me which app I'd like to use by default, so I chose Photoshop CC 2015. However, the thumbnails then disappeared to be replaced with Photoshop icons.I'm thinking of trying to remove the default file association for.psd images, by deleting the registry keys as shown in this answer:This involves deleting HKEYCURRENTUSERSoftwareMicrosoftWindowsCurrentVersionExplorerFileExts.psd and/or HKEYCLASSESROOT.psd. If I do this, will I be able to set Photoshop as the default program again (with the Photoshop icon showing on.psd files) in case the thumbnails don't come back?UPDATE:The method I tried didn't work anyway.psd files still had the Photoshop icon on them. Please also note, that you might need to open the file in PS CC 2015 once before he detects the thumbnails correctlyYou also need to tell Photoshop in the settings that the files should always be saved together with an preview image(set this to off if you like small psd documents)And as pinted out correctly: You can export keys by right clicking and exporting as.reg fileWhen you want to restore the settings just run the.reg file as administrator and all keys and subkeys will be updated to the state they have inside the reg file. I have finally found a fix that works for me. I found a site that would allow you to download the older version of Adobe XL reader. Before installation I de-installed Adobe DC.

Then installed the XL version. Went to Windows explorer to locate a.pdf.

Right clicked the file to select open with Adobe XL, then closed it. Closed explorer then reopened.All.pdf files now display thumbnails.Set XL not to update else you will have the same problem again.I will keep the old copy of Adobe XL until this problem is resolved.

Thumbnails Not Showing In Windows 10 File Explorer (Image and Video) When you open a folder with photos or video files in Microsoft Windows 10 File Explorer, you will normally see thumbnails (reduced-size versions of photos or videos). Thumbnails will appear for almost all common video formats (e.g., MP4, AVI, MKV, WMV, FLV, MPG, and MOV) and image formats (e.g., JPG (JPEG), PNG, GIF, and PNG). In your Windows computer, File Explorer may not display PDF thumbnails, and instead show only the default icon assigned for PDF files. This might happen even if you’ve the option Always show icons, never thumbnails unchecked in the View tab of Folder Options dialog.
