Fix Can T Change Diagnostic Data To Full In Windows 10

The most common cause is the “AllowTelemetry” registry value being set to a low level, with other causes including the Connected User Experiences service being turned off or privacy tools causing conflicts. Before moving on, check if you can log in to the Windows Insider website with your credentials. Also, make sure your Windows is up to date.

1. Enable Connected User Experience Service

The Connected User Experiences and Telemetry service is required for diagnostic data to work. If it’s not running or is disabled, you can run into this problem. Enabling and starting the service should help.

2. Remove the Conflicting Applications

You may not be able to set Diagnostic data to Full if a privacy tool (such as Spybot Anti-Beacon, O&O ShutUp10, or System Mechanic) blocks telemetry. Adjusting the app’s settings or uninstalling it usually fixes the issue. First, check the Apps list in Windows Settings to find any such tools. If you use Spybot, disabling its Immunization feature may resolve the issue. If you use System Mechanic, try enabling Personal Data Collection and Sharing (Toolbox > Protect > Privacy Shield).

3. Enable Other Diagnostic & Feedback Options

This issue can occur if related Diagnostic & Feedback options (like Inking and Typing) are turned off. Turning them on can help.

4. Edit the Group Policy to Allow Telemetry

Telemetry is required for diagnostic data collection. If it’s disabled or misconfigured in Group Policy, you’ll see this problem. Enabling it in Group Policy should help. If you use Windows 10 Home, you may need to install the Group Policy Editor.

5. Delete Tasks in Task Scheduler and Edit the Hosts File

A scheduled task (often from a privacy tool) can block telemetry changes, and entries in the Hosts file can do the same. Removing those tasks and cleaning the Hosts file can help.

6. Edit the Registry Keys

If none of the above worked, you can edit the registry to fix the problem. Warning: Proceed with care and at your own risk. Editing the registry requires caution; doing it wrong can cause permanent system issues. Before you start, create a backup of your registry. Also, close all apps and the Windows Settings app.
