I love the Windows 7 taskbar thumbnail preview because it shows the contents of a window (though only a thumbnail) and aids in quickly swapping open windows. However, you may have a different perspective towards it and may consider it a sheer disturbance while you are working.
If that’s true, let me tell you that you can easily disable the thumbnail preview. Having done that, you will see only the title of the window when you hover on an icon on the taskbar (like one shown in the image below).
Here’s how you may configure the same look for your computer. Before that, let us also see how a thumbnail of the above appears to be.
