I am concerned about how MS uses the data they collect. How do they determine what is sold to third parties? MS probably uses all the tools at their disposal today to keep cloud storage protected but as they have demonstrated time and time again, they create systems that are loaded with security holes. The only time their OS and apps get total scrutiny is when MS sells their OS to government agencies that require absolute protection from outside intrusion. In this case the NSA scours the OS and closes the vulnerabilities for them. No doubt there is also an in-depth script that runs on all those agency systems that blocks all the remaining data collection. I sure would love to have access to those scripts. Without all that, I decided to select certain websites, IP addresses and ports to block. I block the following URLs on W7 ... watson.telemetry.microsoft.com vortex-win.data.mcirosoft.com ssw.live.com settings-win.data.microsoft.com reports.wes.df.telemtry.mcrosoft.com oca.telemetry.microsoft.com.nsatc.net I have seen a W10 list but not a W7 list. For W7, these are all I could find. The one with the most activity every month is vortex-win.data.microsoft.com.
