Windows Media Center?!?

Hi, I have an ASUS laptop and it had Windows Media Center already on it. I installed "internet TV" and it automatically put a box on the top right of the desktop. It had was a slide show of all of there TV series and movies and sports. It was pretty cool, but i accidentally got rid of it by pressing the ex on the corner. i've shut off my computer and turned it back on again to see if it world reappear but it didn't. How do i get it back up on my desktop? Thanks!
