The Connected User Experiences and Telemetry, originally called Diagnostics Tracking or DiagTracK is a Windows service that runs automatically and sends data to Microsoft. As far as we can tell, this service may be safely disabled for added privacy. This article will show you how.
Delete Windows 10 Diagnostic data
We begin by deleting the data that has already been collected. To do this, press “Windows Key + S” and type “privacy” and click on “Privacy settings“.
On the left side, click on “Diagnostics & feedback” then scroll down to the “Delete diagnostic data” section and press the “Delete” button there.
Disable the Connected User Experiences and Telemetry Service
Now that you have deleted the previously collected data we can disable the Connected User Experiences and Telemetry service so that it no longer runs. To do this, press the “Windows Key + R” and type “services.msc“. Scroll down and locate the “Connected User Experiences and Telemetry” service and double click on it to open its properties. Change the “Startup type” from “Automatic” to “Disabled“.
If the service is still running you may click on “Stop”, then “Apply”, then “OK”. Note, you may need to restart your computer to have these changes take effect.
