Big Brother

Windows 10 is built around services that require network connectivity, from the virtual assistant Cortana to OneDrive cloud storage, in addition to the Windows Store for downloading apps.
Microsoft also relies on the OS being able to send back user data in order to personalise these services, for instance to improve Cortana's voice recognition.
This data collection has attracted criticism in some quarters for being too intrusive and for mostly being enabled by default. Most recently concerns were raised about the extent of the information being gathered, after Microsoft published a blog in which it listed the number of minutes users had spent browsing the web and how many questions had been asked of Cortana.

In Windows 10 Enterprise, Version 1511 or Windows 10 Education, Version 1511, you can configure telemetry at the Security level, turn off Windows Defender telemetry and MSRT reporting, and turn off all other connections to Microsoft services as described in this article to prevent Windows from sending any data to Microsoft. We strongly recommend against this, as this data helps us deliver a secure, reliable, and more delightful personalized experience.
