No, I didn't. I just searched and downloaded it. I'll check to see if I have that app.
In case you don't know yet, to display all apps, right click on the Start screen somewhere outside of the tiles. You'll see a bar appear at the bottom of the screen and a button titled "All apps". Click it to see all apps. Or, just type
movie anywhere on the Start screen and that should bring up the button for Windows Live MovieMaker.
