b. Desktop App Submission. You may submit an app description for one or more desktop apps to the pre-release version of the Windows Store. Notwithstanding anything else in this agreement, you understand that Microsoft will not offer any
desktop apps through the Store and only Metro style apps are made available through the Windows Store. Microsoft may, but is not required to, list the desktop app in the Windows Store together with a link you provide, to a website where users can acquire the
app. You are solely responsible and agree to maintain that website and provide an updated link to Microsoft if the url changes. Desktop apps are any apps built using APIs other than the
APIs for Metro style apps that run on Windows 8.
