Windows 7 Taskbar Thumbnail Customizer is a popular, lightweight third-party utility created by Kishan Bagaria that allows you to easily change the size, spacing, text height, and delay times of your taskbar hover previews. Instead of manually altering complex Windows Registry strings, this tool provides a safe, simple slider interface to adjust how your application previews look. Key Customization Features
The utility lets you modify several unique elements of the taskbar previews:
Thumbnail Size: Increase or decrease the maximum and minimum width/height of the preview window.
Spacing: Change the horizontal and vertical gap distance between multiple open window previews.
Margins: Modify the top, bottom, left, and right border spacing around the thumbnail images.
Text Height: Adjust the font layout sizing for window titles.
Delay Time: Speed up or slow down how many milliseconds you must hover over a taskbar icon before the preview appears. Step-by-Step Guide to Using the Utility Create a Restore Point
