Microsoft systematically collects usage data from every user of Windows 11 or Windows 10. It is standard operating procedure. Microsoft uses this data on which apps you use, which settings you have chosen and what websites you have visited to better understand how their customers use their operating system. Presumably, Microsoft does this so they can make improvements. The data is collected through the Telemetry System.

While the intention of this data collection for the Telemetry System is generally harmless, it still involves the collection and storage of your personal and private data regarding how you interact with your PC. Using standard settings, you cannot prevent Microsoft from collecting data for their Telemetry System. However, if you have the correct version of the operating system, a quick hack of the Windows Registry file can shield you, and your private usage data, from Microsoft completely.
Turn off Telemetry data collection in Windows 11 Home
Unfortunately, Microsoft does not allow Windows 11 or Windows 10 Home edition users to completely turn off the collection of telemetry data. However, those users can still limit some optional data collection through System settings.
Open the Start menu in Windows Home and select the Settings app. In the left-hand navigation bar, select Privacy & Security and then scroll down the right-hand list of items to find Diagnostics & Feedback, as shown in Figure A.
Windows 11 Home edition users can limit some of telemetry data collection by turning off the Send optional diagnostic data setting.
Turn off Telemetry data collection in Windows 11 Professional
Users running the Enterprise, Education or Professional editions of Windows 10 or 11, or users running Windows Server 2016 or later, can completely disable telemetry through an edit of the Windows Registry file or through the Group Policy Editor.
