Disable and Enable taskbar thumbnails

In Windows, if you hover your mouse or touchpad over a program that’s open and running in the taskbar, a small preview appears. If it’s something that annoys you, here’s how to disable it. If it’s something that you like that isn’t working, here’s how to get it back.

There are a few methods to make the taskbar previews stop appearing, most notably increasing the delay in the amount of hover time before a thumbnail appears.

The method involves making changes to the Windows Registry. It’s good to have a system or file backup before editing the registry and back up the registry itself before making changes. Directions to change the registry entries, back up the registry, appropriate legal dire warnings and downloable one click registry hacks are available at this How-To Geek article.

For the most part, that method works, but at times it fails. That method works fine on my laptop, but doesn’t work in my Windows 10 dual monitor setup – one monitor has no previews, the other one shows thumbnails when the mouse cursor gets near the taskbar.
After some looking around, I found a batch file that works to disable taskbar thumbnail previews, and to easily reverse the process if I ever want them back. Instead of adjusting the hover time, the batch file works to disable the preview window.

The batch file is easy to use; download the file that you want (or download both) and run it. That’s it. The file and its contents are listed so you can see what the file does. A tip of the hat to Brink at tenforums.com for eliminating another major annoyance.
