Windows 7 - Taskbar - Pin or Unpin Program Links

Question

As in title, is there any Win32 API to do that?

Answer 1

In the comments of a Code Project article it says all you have to do is create a symbolic link in the folder "C:\Users\Username\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar".

But it appears to generally be unsociable practice, as the other comments here have noted.
