In Windows 11, you can change your diagnostic data setting to control how much information your PC sends to Microsoft.

Diagnostic data is information that helps Microsoft identify and fix issues, improve Windows, and enhance its security features. Windows 11 offers several levels for this data, including Basic and Full.

Opting for Basic diagnostic data sends only necessary information to Microsoft, like device specifications and quality-related data, helping them troubleshoot problems. You can adjust these settings easily in Windows 11’s privacy options.

This tutorial guides you through modifying your diagnostic data collection settings, ensuring you have clear control over what your PC reports.

⚡ Quick Answer

Go to Settings, then Privacy & security, and select Diagnostics & feedback. Here, you can choose between “Required” and “Optional” diagnostic data settings. “Required” sends only essential information, while “Optional” includes more details to help improve Windows.

What is Diagnostic Data?

Diagnostic data in Windows 11 is like your computer sending reports to Microsoft to help them fix problems and make Windows better.

There are two main types:

  • Required diagnostic data: This is the basic info needed to keep Windows safe, updated, and working. It includes your device’s setup and if it’s running okay.
  • Optional diagnostic data: This is more detailed. It can include extra info about your device, how you use apps (called “usage data”), and more detailed error reports. Sending this data helps Microsoft find and fix problems faster, which in turn makes Windows better for everyone.

Even if you only send Required data, your device stays secure and works normally. The choice is about how much extra information you’re okay with sharing to help improve products.

Ready to take control? Here’s how to adjust your diagnostic data settings in Windows 11.

  1. Open the Settings App

  2. Locate Diagnostics & feedback

    In the “Privacy & security” section, find Diagnostics & feedback. This is where you control what Windows sends to Microsoft. Click on it.

    Adjusting the diagnostic data setting in Windows 11 lets you choose how much information your PC sends to Microsoft.

    Choose the option that you’re most comfortable with. If you’re unsure, selecting “Required” is a solid starting point.

    Practical Tip: If you’d like to know more about what “Optional” data includes, look for links on this screen. Microsoft usually provides more details there.

    Warning: You might need to restart your PC for these changes to fully work, especially if you switch between Required and Optional. Windows will usually tell you if a restart is needed.
