Once you set up Skydrive on Windows 8, you'll want to active Skydrive on IFTTT.com if you're using it for automation (I've written about this very cool app before.) It has many cool things that you can do (many like you can do with dropbox.) I'm using Skydrive for some things with school.
If you have Windows 8 in your lab. you'll want Music Maker Jam - a sort of Garage Band" for Windows 8. It doesn't seem to have the complexity but it is a great thing for creating and has a whole different feel. Install it in labs for students to mix their own music.
Another great app for Windows 8. The Weather channel.
If you have Windows 8 and touch screens like I have in my computer lab. Fresh Paint is one you'll want to have. It supports up to 5 fingers and you can mix colors. Yes, there's an in app purchase, but I'm going free for now. Sort of like an Art Rage.
The Google Search app on your start screen. I have Chrome but also want to have this search engine (in addition to Bing) on my Windows 8 computer start.
