Since updated from Windows 10 to 11, if i have 1 JPG and 1 MP4 file in each folder, and when i preview my file folders on File Explorer, it shows a thumbnail of the video but not photo. Can I change in the other way around (ie. show thumbnail of photo, BUT NOT videos) on the thumbnail?

 

Windows Explorer crashes and thumbnails problem

Hi, I hope you can help me.
Windows Explorer is no longer showing thumbnails on files played by Windows Media Player. I've run cmd and regsvr32 shmedia.dll and regsvr32 shimgvw.dll. That seemed to solve the problem...but it created a different one. Now when I try to open a folder on an external hard drive it crashes. I read in an old 2008 post it was an avi file causing the problem and suggested the run cmd regsvr32 /u shmedia.dll. That solved the opening problem but recreated the thumbnail problem. Any help to achieve both functions would be greatly appreciated. Thank you.

 

Video thumbnails not appearing on Windows 10

A few months back the thumbnails for my video files (.mp4) stopped appearing and now just appear as the stock video icon after I believe I downloaded and installed WinRAR. However, my image files (.jpg, .png, and .gif) are still fine. Over time, sometimes when I have downloaded a video or gif, suddenly the videos in my downloads folder would be restored and after I placed some videos in the video folder, they were restored too. However, this was not the case for videos in other folders that I have that I primarily use. Today I had a lot of videos in my downloads folder with thumbnails but after I downloaded another video suddenly now none of my videos in ANY FOLDER have thumbnails, even the ones in the video folder but my image files are still fine and all have their thumbnails.

I have tried pretty much every solution the internet lists, such as restoring file explorer to default setting, making sure it's set to thumbnails not icons, clearing the thumbnail cache, using disc clean up, and now even an SFC scan and restarting file explorer but nothing has worked. Did antivirus scans with multiple pieces of software and none of them detected anything. I'm not a very tech savvy person so I have no clue what's wrong and why nothing will fix it. I have seen a few articles mention messing with OneDrive but I never use it. However, looking at OneDrive it does have an error icon on one of the folders with videos it but it does not even list other folders that also are having this issue. I have never had this issue on any of my previous devices. Is it possible that the WinRAR I downloaded caused this? But then how come nothing fixes it even though I deleted WinRAR almost immediately after I downloaded it? Does anyone have any suggestions?
