How to Turn Off the Diagnostic Data in Windows 11

The App Diagnostic is a part of the Windows OS, responsible for obtaining certain application information and transmitting it to Microsoft. The data may include the application's name, package name, the username associated with the application, the application's memory usage, and certain processes connected to it. The goal is to use the information to make these applications more stable, efficient and optimized. However, some users may not wish to share such information with the tech giant and would wish to stop App Diagnostics. Fortunately, doing so in Windows 11 is a relatively fast and easy process. 

Turn Off the App Diagnostic

  1. Go to the Start Menu and open 'Settings.'
  2. Select 'Privacy & security.'
  3. Select 'App Diagnostic.'
  4. Disable the App diagnostic access via the corresponding toggle. 

Turning Off the App Diagnostic for a Single Application

Instead of stopping the feature altogether, some users may prefer to prevent it from getting data from a specific application only.

  1. Open the Start Menu and select 'Settings.'
  2. Open 'Privacy & security.'
  3. Go to 'App Diagnostic.'
  4. Enable 'App diagnostic access' if it has previously been disabled.
  5. Now, select only the apps that you wish App Diagnostic to extract data for while leaving out the apps you wish not to be tracked. 

Deleting the Diagnostic Data

Users may also delete the diagnostic data that has been already collected by Microsoft.

  1. Press the Windows button + I on your keyboard to open the 'Settings' window.
  2. Open 'Privacy & security.'
  3. Go to 'Diagnostics & feedback.'
  4. Locate the 'Delete diagnostic data' option and click on it.
  5. Confirm your decision by clicking the 'Delete' button.
