I have been annoyed by needing to setup my taskbar pinned items every time I set up a new Windows 7 install, so really wanted to find out where they are stored. They are buried pretty deep: C:\Users\**Username**\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar
So now I will be able to keep a copy of a bunch of shortcuts handy and just copy them in there. I'm thinking cmd, Notepad, Calculator, several Office apps, Irfanview, and Paint will be priorities for now.
