If you're paranoid, just block all MS telemetry, diagnostics, and feedback using host file or other 3rd-party Internet-access-blocking software.

The How-To Geek explained this by pointing out that the 'Diagnostics & feedback' was set to Full at the time. Microsoft make it quite clear that this setting will send all that info. Just set it to Basic.

...there’s a simple explanation: Microsoft also collects a history of applications you launch through Windows 10’s diagnostics...
...Windows 10’s default diagnostic setting, “Full,” says it sends “info about websites you browse and how you use apps and features,” so this data may just be sent to Microsoft through Windows 10’s normal telemetry....
