Windows 10: Taskbar Live Preview Stopped Working

I am at wits end, and am loathing the option to reset windows, but I don't know what else to do.

The windows taskbar works perfectly, except for the missing window previews when I hover over the icon of an open program. All other aero features work perfectly. When I hover over an open program, I get nothing or just a small box with text. E.g. If I hover over the Steam client, I get a tiny white box that says "steam". That's it, and even that doesn't always show up depending on the program that I am hovering over.

Throuble shooting tactics that I have tried.
-Reboots
-Registry Edits
-This command in an Admin Powershell - Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
-Made sure that it was enabled in Performance options
-Double checked Taskbar and Start Menu Properties
-Probably more that I cant remember because I am about to punch my monitor.
-Ran sfc /scannow in an Admin Command Prompt

I LOVE Windows 10, but it apparently HATES me very much. If anyone has any idea on what other options are available, please let me know. I have so much set up and would hate to reset windows as a hail mary that may not help anyways.

P.S. Why is this editor overtyping?

EDIT-1: Added one more troubleshooting step I forgot to mention.

Taskbar Live Preview Stopped Working Properly

This happens to me too and only happens when I have a 2nd monitor plugged in. It doesn't happen when I'm just using the laptop screen. It doesn't happen right away but only a little while after reboot. The taskbar preview just stops working. A related symptom
is that when this happens, the tooltip is slower to appear and takes longer to disappear. It is a brain-melting, infuriating bug (one of many in Windows 10) and I am shocked that the Anniversary Update did not fix it.

I am not about to do a System Restore because I am 100% certain that the problem will come back eventually after I install Visual Studio or some new version of some program. Quite simply, this bug shouldn't exist regardless.

When it comes to step 'g', should I copy the files highlighted files in the screenshot below or not?

 

I found a new bit of interesting information. It is explained in this video below that I uploaded to my Youtube channel.
It is less than 30 seconds if you guys wish to see it for a better understanding, but a basic summary is that the previews do not work when hovered over, but if I click the program icon and it has more than 1 window open, it will display the preview. It will not display the preview if both conditions are not met.
