A few years ago we featured a tool to increase the size of your thumbnail previews in Windows Vista, but unfortunately this application doesn’t work correctly in Windows 7. However, there is a new tool for Windows 7 that lets you customize your taskbar thumbnail previews even more in Windows 7. With it, you can change almost anything about your taskbar thumbnail previews. The default taskbar thumbnails are nice, but may be too small for users with vision problems or with very high resolution monitors. Whatever your need, this is a great tool to make the thumbnails looks and work just like you want.
Let’s get started
Download the Windows 7 Taskbar Thumbnail Customizer (link below), and unzip the files. Run the Windows 7 Taskbar Thumbnail Customizer when you’re done. Simply double-click on it; you don’t need to run it as administrator.
Now, you change the size, spacing, margin, and delay time of your taskbar thumbnails. The Delay Time setting is very handy; to speed things up, we set it to 0 so there’s no delay between when you mouse-over a taskbar icon to when you see the thumbnail. Simply drag the slider to the size (or time in the delay settings) you want, and click Apply settings. Windows Explorer will automatically restart, and your new taskbar thumbnails will be ready to use.
Here is the default Windows 7 thumbnail preview of a video playing in Media player:
And here’s the taskbar thumbnail enlarged to 380px. Now you can really watch a video from your taskbar thumbnail.
The larger taskbar thumbnails show up a little different in Internet Explorer. It shows a larger preview of your active tab, and smaller previews of your other tabs. Notice also that Aero peek shows the tab you’re hovering over in Internet Explorer, but the tab name in IE’s toolbar doesn’t change to the one you’re previewing.
Here we increased the width between the thumbnails, while keeping the thumbnails at their default size. This could be useful if you have trouble selecting the correct preview, and we can imagine it would be a very useful modification on touch screens.
And, if you ever take your changes too far, and want to revert to your default Windows 7 taskbar thumbnail previews, simply run the Customizer again and select Restore Defaults. Windows Explorer will restart again, and your taskbar thumbnails will be back to their default settings.
Conclusion
This tool makes it safe and easy to change the size, spacing, and more of your taskbar thumbnail previews. And since you can always revert to the default settings, you can experiment without fear of messing up your computer. If you’d prefer to change the settings manually without using a dedicated application, here’s a list of the registry changes you can make to accomplish this by hand.
