Purpose: Clear or create your own pinned program icons in the Windows taskbar
In a case where you need to alter the windows taskbar, you will come to notice that there is actually no clean way to script the Windows Taskbar. This operating system object is meant to be edited by the user only with no API for programs or scripts to alter it. Hence taskbar customization is instantly an OS tweak. I recommend caution and deeper understanding of Windows 7 OS.
