"Like many other things in Windows Phone 7, we're taking a different approach to updates than we have in the past with Windows Mobile. To start with, we're going to leverage the world-class infrastructure we already have with Microsoft Update today and use that to deliver updates directly to Windows Phone 7 phones - no more worries about figuring out where to go to download an update. We're also making it much easier on our partners (OEMs and Mobile Operators) by establishing a single, consistent update process that they can take advantage of, meaning they don't have to be responsible for their own individual update creation and delivery like they've had to do in the past. So it's really a win for everyone.



We've also built in a notification that pops up right on the phone that tells you when an update is available. When you see that, you connect your phone via USB cable to a computer running the Zune client software. At that point it's literally just one click and the update is downloaded and transferred to the phone, a restore point is created, and the update is installed, all done automatically."
