> Cortana is your personal assistant. Cortana works best when it can learn about you and your activities by using data from your device, your Microsoft account, third-party services and other Microsoft services. You can choose whether to enable Cortana, and you can turn Cortana off at any time.

> Windows 10, rather than residing as a static software program on your device, key components of Windows are cloud-based, and both cloud and local elements of Windows are updated regularly, providing you with the latest improvements and features. In order to provide this computing experience, we collect data about you, your device, and the way you use Windows. And because Windows is personal to you, we give you choices about the personal data we collect and how we use it.
