How to disable Windows 11 telemetry to improve performance

What does Windows 11 telemetry do?

Telemetry is a Windows 11 service through which Microsoft collects information about system operation, program usage data, personal data, and any other system events in order to diagnose problems and improve its products.

Despite the fact that it runs in the background, it consumes memory and processor resources that can mean a drop in the general performance of the computer.
