Ultra-StarWare, Inc. (a company without a company website, apparently) has released a tutorial app to the Windows 8 app store that covers System Center Operations Manager 2012. Operations Manager 2012 Learning Roadmap utilizes the Windows 8 interface to deliver OpsMgr newbies with the necessary information to start using the product.
You can just start learning by navigating the tiled front menu, or use the Windows 8 Search function later on to go back and review or recapture information you read about earlier.
The app is free and runs on x86, x64, and ARM. You can locate it in the Windows Store by searching for "operations manager," or use the link below.
