So you need to get that pinned?
Starting to roll out the official producting Win7′s and one of the interesting things is not all icons lend themselves to being “pinned”. On our CCH tax icons I have to build “pinable” shortcuts. In particular I have to put the word explorer in front of the shortcut url and then I get the ability to pin it to the task bar.
