I just added it and so far, things seem to be running normally. I will assume Microsoft decided to leave it out in order to shrink the install footprint of Windows 8 for mobile devices.... I was a little surprised when the RP was shown to not include Windows Media Center. Since I had thought about using it on a HTPC, that would have been or will be unacceptable. Whether Microsoft is going to charge to add it after final release, is yet to be seen. Hopefully, they will allow adding the normally included utilities without having to pay extra.
