Windows 10: Windows Preview Pane Has No Previews. Standard Fixes Not Effective

The usual recommendations for not seeing file previews in the Windows Preview Pane have not worked in this situation. Additional knowhow needed. Windows Version 1903. OS Build 18362.1082 Below are the usual recommendations in online articles and forums about this. I HAVE DONE ALL OF THESE. No Change. No Result. No file previews. I even attempted individual file type fixes for .txt .jpg, .html. etc. No previews! 1. Enable Preview Pane 2. Enable Show Preview Handlers 3. Disable Always Show Icon settings 4. Change Visual Effects settings 5. Run System File Checker: CMD Code: sfc /scannow 6. Change the File Explorer Startup Mode: Set "File Explorer open to This PC" and not "Quick Access". It was already set correctly, as like the ones above. 7. Reset Folder Options 8. Use PreviewConfig: it's a utility I had to download, it didn't do anything noticeable. So I did all that. My settings were probably already correct for them because I've done this each time a file type lost its preview pane ability. One day there was no PDF previews (uninstalled Adobe Reader hoping Libre/Open offices might substitute), another month no HTML previews nor .docs, not .txt previews, finally recently no images). CUSTOM SYSTEM NOTE: I have take great pains to remove some features of windows including the app store, the apps (not the programs), disabled updates and update checking. So please do not suggest that I reinstall windows, or update. The goal here is a functional stable system without those invasive features. I'm aiming for a computer that does nothing online unless I direct it. That said, your help discovering the cause of the broken preview pane is greatly appreciated. I'm not sure if it was one thing, or many file types falling off over time as I reduced my reliance on the industry leading programs. - - - Updated - - - Just to be clear, the Thumbnail function works okay. (Unless you're a .png or .jpg - Brave and other programs destroy thumbnail function? WTH! This is "The" OS for planet Earth?)

When you say "Windows Preview Pane" do you mean File Explorer preview pane? If so then have you enabled File Explorer preview pane?

 

Windows 7 Preview Pane

I use the preview pane quite often so I can watch videos without having to launch an application to play them. I do this with mostly with tutorials. Most of the tutorials were in quicktime format; quicktime takes a significant amount of time to open on my system, so I used format factory to change them into MP4's (they will play in the preview pane). Just out of boredom, I installed a new convert, called CoverterLite. Now every single video that I converted causes WMP to crash even inside the preview pane. If I were to change my default media player would that affect to preview pane as well? Or does it require so registry editing?
