Explorer Preview pane image will not resize

I'll use the explorer preview pane regularly. I have multiple installs of windows 10 on different machines. On one in particular, I cannot get the preview image to resize/scale up when I drag the preview pane to be bigger. The default space it takes is fairly narrow, which is fine if you just want a rough idea. However, sometimes, I need to see the preview image in a bigger size. In most other installs, the default behavior is that dragging the preview pane border to the left makes the pane itself bigger, and the image being displayed inside scales up to fit the space (in almost all cases. Some exceptions). On this particular install, no matter what the size of the preview pane, the source image remains the same size. I can have the preview pane taking up 3/4 of the explorer window, and the preview image will still be the tiny size it was at default. I've seen this on other installs before, but in those cases, it was (oddly) only jpeg images that had this issue. Other formats resized. This has persisted across multiple builds of win 10, so not just a bug in the build (another machine with the same build doesn't have the issue). In fact, I just had the latest build update. Any ideas out there? It's particularly important to me because I have ridiculous amounts of images where there may be what appears to be an identical shot 20+ times at a glance, but with important differences I could tell them apart with if the preview was bigger.

Here is a screen shot of what I mean. If I drag the preview pane as far right as possible to minimum size, that preview image will be basically exactly the same size

Hi, is this the same in Safe Mode?

As I understand it, Safe Mode is no longer available in Windows 10. Tickling F8 (I think that was the key) does nothing. If I am wrong, how to get it please?

Sorry for the long gap on this thread. I was using a different pc for a while, so this issue kind of fell off my radar. However, now I am back using the PC that has the above issue and I have no other choice. Worse, a large chunk of what I need to do will involve working with and sorting through TONS of media and pictures. To the point it is not practical to open each one, and the thumbnails aren't quite large enough to help distinguish which one I need without opening them. (yes, even with the thumbnail size maxed). The result is the same in safe mode. Now, does ANYBODY have any ideas or clues whatsoever? Yes, the easy answer most will reach for is "re-install". I would really prefer to avoid this, as I have multiple assets that I will not be able to re-install with a blank slate and some other things that will make it prohibitive.

I have a feeling it's probably not some super obvious straight forward, easy to change setting the way windows 10 tends to simplify things for the average user. I'm also on the newer build of windows 10 16232.r2. And I'm pretty sure the windows build has been updated and installed at least 3 or 4 times since typing the original thread message. Not quite a re-install obviously, but with a new build image being rolled out multiple times...seems unlikely it's something that just needs fresh system files. I could be dead wrong, but for some reason, I have a hunch this will end up having to be resolved by some registry tweak or change. But I need someone in the know to point me in the right direction

This is an old thread but my issue is EXACTLY the same, and I have found no help anywhere. Most posts address images not appearing at all, or PDF viewers not working. Has anybody ever found anything that has caused image preview on the Windows Explorer (for either Windows 7 or 10) to stop scaling to the size of the viewing pane? Thanks for any help.

Thanks for the quick response! Unfortunately, just as the OP also answered, same in Safe Mode. I've tried low res, medium res, no scaling of text, single monitor vs dual -- no matter what all images, whether they are large or small, show in the preview as a set size, which is relatively small, and will not "grow" as you resize the preview pane to even a very large size. Laptop has absolutely no problem (Windows 10) and a different computer using Windows 7 also no problem. Any ideas?
