Windows 10: Window task bar live preview hover not working?

I need help. I used to be able to minimize a window, then hover over the icon in the task bar, and it would show a live video feed at the bottom of the task bar. Now when I have a window minimized, and I try to hover over it in the task bar, it only shows a thumbnail and not a live video feed. But when I have the app brought up or opened, then it works like it should. I've tried changing the view options in file explorer, tried changing and creating DWORD or whatever in the registry and every attempt is failed. Does someone know the exact solution to this problem?

No Task Bar (hovering) preview, no peeking, no full screen is on hovering over and clicking

When there is no window opened, hovering over taskbar app icons, a preview is shown, but on hovering over preview no full window is opened, and no peeking is done, and also clicking on that small preview, no window opened.

1. And whenever there is a window is opened then hovering over taskbar icons doesn't gives any preview of the window.
2. But it still opens window, on just clicking on task bar icons ( i.e. working fine ).

And when two windows of any app is being opened and if minimized any of them then you can not maximise that minimized window...???

• And when both windows of same app is being minimized then hovering over task bar icon of that app still shows those two previews, but clicking on any preview doesn't provide anything, and thus it all means after minimizing those two window of that app you
  can not recover any of the window.

Basically the problem is I'm not able to open window ( or make full ) from any task bar preview and the First (1.) one also of first paragraph.

Win 10 suddenly stops Task Bar Browser Icons Popup on Mouse Hover

Hi, I understand you do not see taskbar thumbnails when hovering over an active icon on the taskbar.

You could use this recommended reputable free tool to try re-enabling that - by unchecking the box of course.
