Last week I came to know about windows Control Panel Extensions via RideRz blog http://zaanrider.wordpress.com which had 112 run commands. And the first one that I experimented with it was the Desktop properties window that you get once you right-click on your Windows Desktop, the file is desk.cpl, And went on to find that all the items that are listed on control panel has the same .cpl extension. And they reside in System32 folder. you can explore through the rest of the control panel items and I believe that one should also be able to develop his/her own control panel item as well. So come up with your own Control Panel Extension And take on your Control Panel.
