Normaly when you right-click an item in the taskbar you get the following context menu:

Restore
Move
Size
Minimize
Maximize
---------
Close

But sometimes (small) applications have additional menu item(s) in this contextmenu. I must stop right here and say that I do not like this becuase it usually moves the close menu item from it's normal position so I usually miss the close item. Anywho, for example if you launch the Create GUID tool from VS2005 (Tools->Create GUID), this application has an additional menu item in the context menu like this:

Restore
Move
Size
Minimize
Maximize
---------
Close
---------
About Create GUID...

Even though I do not like this, I would like to know how this could be done. Does anyone here know how this can be done (with managed code)?
