How to Enable or Disable Diagnostic Data Viewer in Windows 11

Windows 11 collects small pieces of information about how your computer works. This is called telemetry. Microsoft uses this data to fix bugs, improve security, and make sure your apps run correctly. It helps them understand if a feature is crashing or if a driver is causing problems.

Why do this? You might want to see exactly what your computer is telling Microsoft.

What happens when done? Enabling the viewer lets you see this data in real time. Disabling it stops the collection of detailed logs, though some basic data is still required to keep Windows safe.

Is the Diagnostic Data Viewer Installed by Default?

No, the Diagnostic Data Viewer is not installed by default on Windows 11. You must download it from the Microsoft Store to use it. Once installed, it works with the settings you configure in the Privacy menu. You can find it by searching for ‘Diagnostic Data Viewer’ in the Microsoft Store app.

Using the Settings App

This is the easiest way to control your data settings.

1. Open the Windows Settings app.
2. Select Privacy & security on the left.
3. Click the Diagnostics & feedback tile on the right.

4. Select the View diagnostic data tile to expand it.
5. Use the toggle switch to turn it On or Off.

Exit the Settings app when you are finished.

Troubleshooting: Cannot Find or Enable the App

If you cannot find the app, ensure you have downloaded it from the Microsoft Store. If the toggle is greyed out, your computer might be managed by an organization or school. In these cases, your IT administrator controls the privacy settings. You can also check if your Windows version is up to date, as older versions may not support the latest viewer features.

Enterprise and Privacy Context

In a business setting, administrators often use Group Policy to manage telemetry. This ensures that all computers in an office follow the same privacy rules. If you are a home user, you have full control over these settings. You can also visit the Microsoft Privacy Dashboard online to manage your data history across all your devices.

Data Management and History

The viewer allows you to see the data history size. You can clear your diagnostic data history through the Privacy & feedback settings menu. Simply click the Delete button under the ‘Delete diagnostic data’ section. This removes the data stored on your device and notifies Microsoft to delete the associated data from their servers.

Using the Local Group Policy Editor

Note: This method requires admin privileges.

1. Open the Start menu, type gpedit.msc, and press Enter.
2. Navigate to this folder path: Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds.
3. Find Disable diagnostic data viewer in the list and double-click it.

4. Choose Not Configured, Enabled, or Disabled.
5. Click OK to save. You may need to restart your computer for these changes to take effect.

Using the Registry Editor

Note: This method requires admin privileges. Be careful, as changing registry settings can affect your system.

1. Open the Windows Registry.
2. Go to the following path: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DataCollection
3. Double-click EnableEventTranscript.
4. Change the value to 1 to turn it on, or 0 to turn it off.
5. If you do not see this item, right-click in the empty space, select New > DWORD (32-bit) Value, and name it EnableEventTranscript.

Save your changes and restart your computer.

Summary

You can manage how much data your Windows 11 computer sends to Microsoft by using the Settings app, the Group Policy Editor, or the Registry Editor. Whether you want to view the data being sent or turn off the collection feature entirely, these steps allow you to balance your privacy needs with the performance of your operating system. Always remember to download the viewer from the official Microsoft Store to get started.
