how to Create Windows 7 Quick Launch Icon With C# ?
Create a .lnk file in the c:\users\mumble\appdata\roaming\microsoft\internet explorer\quick launch folder. Beware that the Quick Launch toolbar is disabled by default in Win7, I don't remember what I did to re-enable it.
Creating the .lnk file takes secret sauce as well. You can find sample code in my answer in this thread.
