&gt; As far as I know they give you the option to opt out of everything<p>The thing we now know as &quot;telemetry&quot; used to be opt-in, and they hide the opt-out control during initial setup behind a thing that is a link but doesn&#x27;t look like one.<p>It can still be turned off after installation in the same exact way as the previous versions of Windows (enter &quot;experience&quot; in the Start menu search box), but most won&#x27;t know that this control exists.<p>All the rest of the things causing people to freak out about privacy are related to Cortana, and the process for turning that feature set on is in-your-face opt-in, where it&#x27;s clear that you&#x27;re authorizing data sharing with them.
