Windows 7 Tips: Retrieve the missing taskbar thumbnails

Before Microsoft officially launched the Windows 7 operating system, it has won the favor of many users with its rich new features and cool display effects. For the "real-time taskbar thumbnail preview" feature, Microsoft is still very interesting, basically supported in all Windows7 versions. 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 taskbar preview thumbnail suddenly disappeared. Move the mouse to the taskbar, and the text will appear as a line-by-line text title. It’s really awkward...

So, how can I get back? Since the previous thumbnail preview works properly, the hardware should be supported. As long as the relevant hardware and drivers are working properly, this problem is well solved. Just change the relevant settings. Here are two ways to solve this problem.
