We have talked quite a bit about SkyDrive and using your Microsoft account for the sign-in and roaming capabilities of Windows 8. These are just two aspects of a broad service infrastructure that you can tap into when using Windows 8 (and Windows Phone, Xbox LIVE, and a host of other services and apps). We want to talk more about the capabilities and features of cloud services for Windows 8 and Windows Phone. To get started, Chris Jones, the VP of our Windows Live group responsible for the development and operations of all of the services and apps, authored this post to introduce the reimagined role of cloud services in Windows 8.
