That said, examining these options is tedious and it will be unclear, to most, which if any of these options is most important to consider changing. That is by design: though Microsoft provides an incredible list of privacy-related options to consider, the most obvious option---for disabling the telemetry data that Windows 11 sends back to Microsoft automatically---is not among them. Instead, Microsoft relies on this data to help make Windows 11 more reliable for everyone.
You can find Windows 11's privacy settings by opening Settings (WINKEY + I) and navigating to Privacy & security. Here, you will find the privacy options organized under the sections Windows permissions and App permissions, below the Security section.
