Toggle Diagnostic Data Settings in Windows 11

When using Windows 11, Microsoft collects diagnostic data to enhance the performance, security, and overall user experience. This diagnostic data includes information about the hardware, software, and system interactions, allowing Microsoft to identify and address issues, improve features, and ensure the smooth functioning of Windows 11

This diagnostic data is crucial for Microsoft to continuously refine and optimize Windows 11, delivering a more reliable and secure computing environment for users worldwide. 

There are two parts to this data: Required and Optional. While you can’t directly turn off the Required data, there is the option to turn off Diagnostic data.

Here is how to do that:

Open Windows 11 settings (Win key + I) and click Privacy & security.
