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

Why do MS Moderators even bother to post in these threads if you have absolutely no idea of how to fix the problem??? It's always the same ol' generic blurb and all it serves to do is make very frustrated and desperate people extremely frustrated people who hate MS.

Please stop with the generic blurbs and look for REAL answers and/or fixes. This would MAYBE restore some faith and confidence in our relationships with MS.  Right now, MS just looks like a greedy corporation who pushes sloppy updates onto its users and couldn't care less about helping them to fix it.

SHAME ON YOU MICROSOFT!  YOU MUST DO BETTER.  THE PEOPLE ON THESE THREADS ARE WHY YOU ARE THE CORPORATION YOU ARE, NOT THE OTHER WAY AROUND.  MY PC COULD JUST AS EASILY BE MY MAC!

HELP!! ANYBODY!! PLEASE!! IS ANYBODY OUT THERE WHO KNOWS HOW TO FIX THIS??!!!!

I'm not an expert at all but I can tell you what worked for me.  I tried all the other advice offered on this thread.

Finally I followed an obscure youtube link and managed to adapt the advice there for me.

I went to my control panel.

then I opened "system" and chose "advanced system settings" on the left hand side

I then clicked on the "advanced" tab and then under "performance" I clicked on "settings"

The video I watched said to make sure that the "show thumbnails instead of icons" block was ticked.

That didn't help me since my little block was already ticked.  (I was also a little ticked off at that stage...)

I then saw that there were four options starting with  "Let windows choose....."  and then "custom".

Mine was ticked as "let windows choose".  I thought I didn't trust Windows anymore and elected to take all its choices away.

So I changed the option to "Custom".

However, since I didn't have the slighest idea on which options to choose, I just left all the same boxes ticked (including the 'show thumbnails instead of icons"

Since I didn't make any changes, the page wouldn't allow me to save or apply my changes.  So I unticked one of the boxes and ticked it again.  I could then apply my changes.

I went back to my windows explorer.  Closed it.  Opened it.

Voila!  My preview was back.

I don't know if this is a real fix.

For all I know, some extra stellar space beams from URANUS hit my PC at just the correct frequency  to fix the problem at exactly the precise second that I opened my windows explorer again.

With Windows,   anything is possible.

But whatever.  It's fixed.

Good luck and may Uranus hit your PC too.

Well Uranus didn't hit my PC. Still not showing PNG files :/

I have never had OneDrive set to "Save space and download files as I need them" and I still have the problem of thumbnails for jpg files not visible. Also, it doesn't matter if the jpg is lower or upper case. Still no thumbnails. visible.

same here!
