Windows 10: Replace taskbar menu with window thumbnails

I'm using the latest version updated at the start of September of Windows 10 Professional on a Dell desktop computer. I have two monitors connected side-by-side. When I hover the mouse over most of the icons in the taskbar at the bottom of the screen, I see little thumbnail images of each window opened in that program/app. But, in the last couple of weeks, when I hover over the SeaMonkey browser icon, I get a tall menu showing the title of each tab opened in each of the four SeaMonkey windows. How can I stop the menu and show little thumbnails of each of the four browser windows?

:)

 

Feature suggestion: Add right-click menu

Suggestion: Please add a Windows 7 Jump-List and/or right-click menu to the GPU-Z icon in the Windows taskbar. Possible menus in it would be "Exit" and "About GPU-Z...".
Maybe also "Switch to tab 1/Switch to tab 2/Switch to videocard 1/Switch to videocard 2" too.
Examples of programs that have such menus are ICQ, Skype, AIM.

NOTE: It seems for a right-click menu, Windows 7 is not needed - it works on WinXP and Vista too.
But even a Windows 7 Jump-list may be good enough.
What do you think?

 

Taskbar Thumbnails

Hello Joe, *Smile

It looks like you may have set your taskbar thumbnails threshold too low by mistake.

Check to see what you have for the NumThumbnails DWORD value, and adjust as/if needed.

Change Delay Time to Show Taskbar Thumbnails in Windows 10


Hello Eddo,

This setting affects the delay time to show both thumbnails and list.

It doesn't affect which one shows though. For that, see: Change Taskbar Thumbnail Threshold to Show List in Windows 10 Windows 10 Tutorials
