Thanks to The Geek’s bounty program we now have an incredibly useful application to increase the Taskbar Preview Pane in Vista. But what if you don’t like the preview panes? To keep everything fair and balanced I will show you how to disable the panes entirely.
Right Click on the Start Menu and select Properties.
From the Properties menu screen uncheck “Show window previews (thumbnails)”. Click Apply then OK and your done!
