Windows 7 Taskbar Thumbnail Customizer

Windows 7 Taskbar Thumbnail Customizer will allow you to customize Windows 7 taskbar thumbnail previews in detail. You can change the size of the thumbnail, its spacing, top, bottom, left, right margins and mouse delay time too!

Find the spacing or margin not to your liking? Go ahead and change them! Or maybe you want to customize the text height! You can do that too. But you have to be careful while making the changes, lest you disturb the balance.

Once you have made your choices, click on Apply Changes. The explorer.exe will restart to apply the changes.

Messed up ? You can click on the Restore Defaults button to reset all settings to Windows 7 default values. It is always a good idea to create a system restore point first, before making any changes to your system – so that you can restore back to a good point, should things not go the way you wanted them to.

UPDATE: 10th Mar, 2010. Taskbar Thumbnail Customizer has been updated to v1.1. This update fixes the default values of the X Spacing & Y Spacing.

Windows 7 Taskbar Thumbnail Customizer v 1.2, has been developed by our TWC Forum member Kishan. Do remember to create a system restore point first before using it.

Windows 7 Taskbar Thumbnail Customizer has been inspired by the blog post at, run by my MVP colleague Ramesh Srinivasan, and the credit for the tweaks used in this app goes to him.

    i think you are mistaken. it should be delay time and not text height.

    FYI – I had a couple users complain that when they had two excel files open, it would actually make them smaller – which it does. My solution was to have them open two excel windows, one for each file and it works fine.

    This program is doing strange things to my computer resolution.

    Please advise me as to how to UNINSTALL the program. I can not find in in the Control Panel Programs list.

  7. You have to just click the Restore button and then delete the program folder. You can also restore your computer back to and earlier restore point.

    This broke Aero Peek on my computer. Tried aero troubleshooter, Windows Destop Management and Themes Services, and restore point, but nothing can bring Aero Peek back to life. I advise just using the registry hacks and to stay away from this program.

  11. Restoring your computer back to the created restore point is the quickest way to do it. Else see
