Unpinning Windows Explorer from Default User

I wanted to change some settings for the Default User and I came across this link.

How to customize the default local user profile when you prepare an image of Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2

So I made the changes on an account and then ran the command mentioned. Windows updates and asked me to input some information again, like the clock and making a user.

So when I logged in again, everything looked as I expected it to, with one exception. There's a pinned link to Windows Explorer in the taskbar. And it's there on any new account I create. I tried removing it from an account and then running the command again but I ended up with the same result.

I then looked up where to find these pinned shortcuts, and oddly enough there was none to be found in the location for the Default User. So I'm wondering if anybody knows how to unpin Windows Explorer from the taskbar of the Default User, when the shortcut can't be found in the folder it should be at.

Sure, here you go.

That won't help, because that's not the problem. The problem is that the shortcut is there on every new account I make, and I want to remove it from the Default User account from which all new accounts are made.
