TDC is a unique icon changer tool for Windows systems that allows users to replace existing icons with new designs based on various themes. With 10 pre-installed themes and the option to download more from the website or create custom themes like futuristic, linux, paper, and more, TDC offers a wide range of customization possibilities.

To use TDC, simply install the application, select a theme from the available options under "Home -> TDC -> Themes," then navigate to screen settings -> appearance -> effects to modify the icons. While the process is straightforward, it's important to note that the tool works best on Windows 98/Me, with partial functionality on 95/NT/2000/XP due to limitations in changing certain icons.
