I can't find a way to do this, and knowing my experiences in the past there prolly isn't way to do this, but I would to setup the taskbar fully during deployment using MDT 2013.
I want to remove the Search Box, Taskveiw, and New apps. I also want to remove all the default pinned apps and replace them with ones I want.
I am really tired of manually doing this each time for each new install.
For the first three, I haven't found a way to do it that doesn't involve just doing it manually when I setup the user.
For the pinning of the apps, I found some ways, but none worked right. They would either completely locked the Start Menu from completely working and/or change on each reboot.
