Windows 10: How to stop previews when hovering over a taskbar button?

.
After last night's Win update, I now have version 1803.

This has broken my Taskbar Tweaker. Therefore, when I hover the mouse over a button, there's now a popup preview.

How can I stop the preview?

Thanks.

Windows 10 taskbar app icon not showing preview (Taskbar Hover preview)

Hi,I found that when I hovered my mouse pointer over the app icons on taskbar. Windows didn't show a preview (a small window above the app icon) of the apps like it used to. I am wondering how to fix this?

thanks

Mouse hover preview is not showing open apps on taskbar

I am running Win 10 on three computers. When I hover a pointer over a taskbar icon of a running app I can see the content of the app...mostly I want to see if some routine has competed when I am running several instances. On two of three computers, this
function works, but on the 3rd it does not.

I simply cannot find the setting on the 3rd that is set differently than on the other two. In fact, it just was functional on the two without my having to set anything to begin with.

How do I enable this preview function?

Thanks.
