Can't preview jpg files in the preview pane -- Windows 10 Fall Update (1709)

Finally found the solution.

Now that Windows 10 has nearly removed the old Control Panel; several items which are only available via the Control Panel are harder to find.

Open the old Control Panel; type into the Win10 Search Field "Control Panel" and then click the result to Open it. Make sure the Categories option is set; then click on Appearance and Personalisation; then File Explorer Options.

A new window will open -- click on the View tab.

The first choice "UNCHECK" Always show icons, never thumbnails.

I have now also found this same setting in the View Menu of Windows 10 File Explorer. At the far right-side of the header ribbon after clicking on the View Tab is an icon labelled Options.

Clicking this -- select the first choice "Change Folder and Search Options. A new window opens. Click on the View Tab; then again UNCHECK the first choice "Always show icons, never thumbnails."

I've had this problem on all my computers.  It only happens on JPGs in OneDrive.  If they're on the computer, but not in OneDrive, they preview as they should.  Eventually, they started working in OneDrive on all 4 of my devices.  This device, I had to reset and since then, it reverted back to not showing previews of JPGs in OneDrive. I've unclicked "save space and download files as I need them" which seemed to work the last time, so I'll see if it works again this time or if something else made that happen, that I wasn't aware of.

Hi,

Have you checked if you have the latest update for your Windows 10? Have you also encountered this after installing Fall Creators Update?

What are the troubleshooting steps you've already done? If nothing yet, let's run the following scans to repair missing or corrupted system files:

• System File Checker

The System File Checker or SFC is a utility in Windows that allows users to scan for corruptions in Windows system files and restore these corrupted files.

• DISM or System Update Readiness tool

The DISM or Deployment Image Servicing and Management can help you fix some Windows corruption errors as well.

We'll be waiting for your response.

Regards.

I have the same problem.  I am a photographer so it slows me down.

I had this same problem in Windows 7, and after scouring the internet for hours (days) and pulling my hair out, finally noticed that it was only .JPG files in all CAPS, not lowercase.

So I guess something changed in a Windows 7 update as well as Windows 10 (and I assume others?), because I have never seen this problem before and some of these JPGs haven't changed since the 90s.
