How to Disable Telemetry in Windows 11? [Easy Steps]

The telemetry process in Windows 11 collects certain diagnostic and usage information to help Microsoft improve system performance, identify bugs, strengthen security, and deliver a better user experience.

While some users are comfortable sharing this information, others prefer to limit the amount of data sent from their computers for privacy reasons.

Although some essential diagnostic information is always required to keep Windows secure and functioning properly, you can disable many optional data collection features through the Settings app, Group Policy Editor, Registry Editor, and Services.

In this guide, you’ll learn what telemetry is, why it exists, and the safest ways to reduce or disable it in Windows 11.

What is telemetry in Windows 11?

Telemetry is Microsoft’s system for collecting diagnostic and performance data from your Windows device. The information may include hardware details, installed drivers, application reliability, crash reports, device configuration, and how Windows features are being used.

Microsoft uses this information to improve Windows updates, identify compatibility issues, fix software bugs, enhance security, and develop new features.

Windows 11 collects two primary types of diagnostic data.

Required diagnostic data is the minimum information Microsoft needs to keep Windows secure, reliable, and up to date.

Optional diagnostic data includes more detailed information, such as enhanced error reporting, app usage, and additional system diagnostics. This type of data can be turned off by users.

If privacy is your priority, reducing optional telemetry is one of the easiest ways to limit the amount of information shared with Microsoft.

How to disable telemetry in Windows 11?

You can disable or reduce telemetry in Windows 11 by turning off Optional Diagnostic Data in Settings, disabling diagnostic features, changing Group Policy settings, editing the Registry, and disabling the Connected User Experiences and Telemetry service. Home edition users can use Settings and Registry Editor, while Pro and Enterprise editions also include Group Policy Editor for additional control.

Let’s explore the steps in detail….

Step 1: Turn Off Optional Diagnostic Data

The easiest place to begin is the Settings app. Windows allows you to stop sending optional diagnostic information while continuing to send only the minimum data required for system security and updates.

Press Windows + I to open Settings. Select Privacy & security from the left pane, then choose Diagnostics & feedback. Locate the Send optional diagnostic data option and switch it Off. Once disabled, Windows will stop sending enhanced diagnostic information to Microsoft.

While you are on the same page, you can also turn off options such as Improve inking & typing, Tailored experiences, and View diagnostic data if they are enabled. These settings reduce additional data collection related to personalization and usage analysis.

For most users, this single change significantly reduces telemetry without affecting Windows performance or security.

Step 2: Delete Existing Diagnostic Data

If Windows has already collected diagnostic information, you can remove the locally stored diagnostic data from your device.

Open Settings, navigate to Privacy & security, and select Diagnostics & feedback once again. Scroll until you find the Delete diagnostic data section.

Click the Delete button and confirm the action if prompted. Windows will remove diagnostic data stored on your device and request Microsoft to delete associated diagnostic information from its servers where applicable.

This process does not disable future data collection by itself, but it helps clear previously collected diagnostic information after you have reduced telemetry settings.

Step 3: Disable Telemetry Using Group Policy Editor

If you’re using Windows 11 Pro, Enterprise, or Education, you can further reduce telemetry using the Local Group Policy Editor.

Press Windows + R, type gpedit.msc, and press Enter. Inside the editor, navigate to Computer Configuration, then Administrative Templates, followed by Windows Components, then Data Collection and Preview Builds.

Double-click Allow Diagnostic Data. Choose Enabled, then select the lowest available diagnostic level supported by your Windows edition from the drop-down menu. On many versions, selecting the minimum available level limits telemetry to essential diagnostic information only. Click Apply, then select OK.

After making this change, restart your computer to ensure the new policy takes effect.

If your computer runs Windows 11 Home, you won’t have access to the Group Policy Editor, so you can continue with the Registry method instead.

Step 4: Modify the Registry to Limit Telemetry

The Registry Editor provides another way to reduce telemetry, especially on Windows 11 Home.

Press Windows + R, type regedit, and press Enter. Approve the User Account Control prompt if it appears.

Navigate to the following location:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DataCollection

If the DataCollection key does not exist, right-click Windows, choose New, then Key, and name it DataCollection.

Inside this key, right-click the empty area, select New, then DWORD (32-bit) Value, and name it AllowTelemetry.

Double-click AllowTelemetry, set its value to 0, and click OK.

Close the Registry Editor and restart your computer.

Before editing the registry, it is always a good idea to create a System Restore Point or back up the registry. This allows you to restore your system if an incorrect change is made.

Step 5: Disable the Connected User Experiences and Telemetry Service

Windows includes a background service responsible for collecting and sending telemetry information.

Press Windows + R, type services.msc, and press Enter. Scroll through the services list until you locate Connected User Experiences and Telemetry.

Double-click the service to open its properties. If the service is currently running, click Stop. Next, change the Startup type to Disabled.

Select Apply, then click OK.

Disabling this service limits additional telemetry activity, although Windows may still collect some required diagnostic information depending on your edition and system configuration.

Restart your computer after completing this step.

Step 6: Restart Your PC and Verify the Changes

After completing all the previous steps, restart your computer to ensure every setting has been applied correctly.

Once Windows starts again, return to Settings, then Privacy & security, and open Diagnostics & feedback. Confirm that Optional Diagnostic Data remains disabled and verify that any additional diagnostic options you turned off have stayed disabled.

If you also changed Group Policy, Registry, or Services settings, Windows should now be operating with reduced telemetry and fewer diagnostic reports being sent.

Remember that Microsoft still collects a small amount of required diagnostic information that cannot be completely disabled on standard consumer editions of Windows 11.

Useful Tips From My Side

Reducing telemetry does not prevent Windows Update from working normally. Your computer will continue receiving important security patches and feature improvements.

Avoid downloading third-party utilities that promise to completely remove telemetry. Many of these programs modify important Windows components and may create unexpected stability issues or future update problems.

Create a System Restore Point before making changes in Registry Editor or Group Policy Editor. It only takes a few minutes and provides an easy recovery option if something goes wrong.

Review your Privacy & security settings regularly after major Windows feature updates. Some updates may introduce new privacy options or reset certain preferences.

If your organization manages your computer through work or school policies, some telemetry settings may be controlled by your administrator and cannot be changed manually.
