How To Turn On or Off Diagnostic Data in Windows 11

Windows 11 automatically sends diagnostic data to Microsoft servers for tracking and troubleshooting. Here is how to turn on or off diagnostic data in Windows 11.

Since Windows 8, the operating system automatically sends diagnostic data to the Microsoft servers regularly. Microsoft then uses this diagnostic data to learn and improve the overall Windows 10 and 11 experience.

For example, If Windows 11 or one of your installed apps constantly crashes, Microsoft receives that crash details in its automatic diagnostic data. That way, Microsoft can learn and fix any issues with the Windows operating system in the next update. Microsoft also gets diagnostic data regarding how you use the operating system and its various apps and features.

You should know that when your computer sends the diagnostic data, it uses one or more unique identifiers. That means Microsoft can use these unique identifiers to distinguish your system from other computers.

If you want to help Microsoft or if you don’t like to send optional diagnostics data, you can turn on or off diagnostic data in Windows 11. It is pretty easy to do. Let me show you how.

What information does the Diagnostic Data contain?

Windows 11 sends two types of diagnostic data. They are the Required Diagnostic Data and Optional Diagnostic Data.

Optional diagnostic data: This is the additional diagnostic data you can choose to send to Microsoft. It includes information like installed software, device health, enhanced error reporting, memory state, system and app crashes, system usage, and more.
