Windows 10: What is the feature that allows me to preview an app when I hover over it's expanded...

:)

 

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.

 

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

Hello Daiyue,

We appreciate the time and effort you have put in to resolve the issue.

At this point, I suggest you to check if the same issue occur when logged in through a different Local administrator user account.



Follow the steps:

• Assuming that you are already logged on to your user account in Windows 10, click the Start button.
• From the Start menu, click your name from the top of the left pane.
• From the displayed options click Sign out.
  
• From the login screen, click to the different user account you want to switch to.

However, if you do not have a separate user account, I suggest you to create another administrator user account by referring to the Microsoft article here: Set
up accounts.

Kindly keep us posted if it helps the Task bar hover preview work on the new user account. This would help us to ascertain if the issue is user account specific.

Thank you.
