I have a CMD prompt shortcut pinned to the taskbar but I can only launch it once? So I have to have yet another icon on the desktop to launch multiple windows? (The same thing applies to many app that I need to launch multiple copies of MsTSC / SSH etc.)
Hold Shift while you click the pinned program.
This will open a new window of the app as opposed to activating the currently open window.
You can launch new instances of pinned programs at the first 9 (or 10?) positions by pressing
Windows-Shift-N, with N being the position from the left.
You can middle click any item on the taskbar to launch another instance.
right-click click on the "Command Prompt" in the popup menu. Tadaa... new command prompt.
