Solved Answer

While it is not a malevolent application, some users find it suspicious why the file uses a respectively large amount of CPU and disk processing resources. Additionally, the file is the component of Windows Customer Experience Improvement Program. Likewise, if not disabled, the file transfers the telemetry data, technical data about your operating system, to Microsoft. The app also restarts with each new Windows log-in session despite the attempts to disable the task completely. Users, who are especially cautious about their privacy in cyber space, are dissatisfied with the application transmitting telemetry information to Microsoft for service improvement purposes. If you happen to be one of them and intend to terminate the application permanently, choose one of the following solutions.
