How to get back the thumbnail of the Windows 7 taskbar disappearing

For the "real-time taskbar thumbnail preview" function, Microsoft is still very interesting, basically all supported in the Windows
7 version . As long as the user moves the mouse over the taskbar, a preview thumbnail will appear, and the visual effect will be unique, but I don't know when the preview thumbnail of the taskbar suddenly disappears. Move the mouse to the taskbar and it will become a line-by-line text title. It looks awkward.

Operation Steps

In the Start Search box, type: gpedit.msc and press Enter to open the Local Group Policy Editor.

Expand “User Configuration”-“Administrative Templates”-“Start Menu and Taskbar”.

In the detail window on the right, drop down the scroll bar and find the "Through the taskbar thumbnail" item.

Double-click to open and change the setting to “not configured” or “disabled”. Then press “OK” to exit.
