Didn't see this reported above.
IP10 on Win7 Pro. Since the install, the Change Icon item in a desktop shortcut's context (right-click) menu fails to bring up the Change Icon dialog for some, but not all, shortcuts but the icon can still be changed in the file's properties dialog via the Change Icon button.
Not all shortcuts or desktop items have the Change Icon item in the context menu, but I don't believe that is new to IP10.
