I have read these:
Adding item to the Desktop context menu in Windows
http://www.informit.com/articles/article.aspx?p=169474
http://msdn.microsoft.com/en-us/library/bb776852(VS.85).aspx
But I cannot find an up-to-date and straightforward piece of information on how to create a context menu item.
I'm sure it's in msdn somewhere, but I can't find it.
Thanks.
There's an article on TSS.
