Don't clutter my desktop with shortcuts!
On my computer, I control my desktop, and I absolutely hate shortcuts to programs on it. I put special files that I access often, and I use it as a temporary space. Sometimes I will put a shortcut to certain folders, but other than that, I like a clean desktop.
I get very frustrated by software that doesn't give me the option of disabling the shortcut on the desktop. Even worse is an upgrade to something that restores a shortcut that I previously deleted.
What puts a smile on my face is when an installer asks me if I want a shortcut on the desktop, and the default choice is no.
