How to Delete Copilot Memory in Windows 11

Microsoft Copilot in Windows 11 can remember certain preferences, conversation context, and activity history to provide more relevant responses over time. While this improves personalization, some users may want to delete Copilot memory for privacy reasons or to reset its behavior.

Copilot memory is typically tied to your Microsoft account and stored through cloud-based services rather than locally on your device. That means clearing it involves removing activity history, resetting the app, or adjusting privacy settings.

If you want to delete Copilot memory in Windows 11, follow the step-by-step guide below.

How to Delete Copilot Memory in Windows 11

Follow the methods below depending on what type of memory or history you want to remove.

1. Clear Copilot Chat History

If you want to remove previous Copilot conversations:

1. Open Copilot from the taskbar or Start menu.
2. Click your profile icon (top-right corner).
3. Go to Settings.
4. Look for Privacy or Chat history options.
5. Select Clear chat history or Delete conversation history.
6. Confirm the action.

This removes stored conversations linked to your Microsoft account.

2. Delete Microsoft Account Activity Data

Copilot may store interaction data through your Microsoft account.

1. Open your browser.
2. Visit the Microsoft Privacy Dashboard (account.microsoft.com/privacy).
3. Sign in with your Microsoft account.
4. Navigate to Activity history.
5. Review stored data categories.
6. Select Clear activity for relevant sections.

This removes cloud-synced activity data associated with Copilot usage.

3. Reset the Copilot App

If you want to remove local Copilot settings and cached data:

1. Press Windows + I to open Settings.
2. Go to Apps > Installed apps.
3. Locate Microsoft Copilot.
4. Click the three-dot menu and select Advanced options.
5. Click Reset.
6. Restart your PC.

Resetting removes locally stored configuration data.

4. Disable Personalization Features

To prevent Copilot from storing future personalized data:

1. Open Settings.
2. Go to Privacy & security.
3. Select Diagnostics & feedback.
4. Disable optional diagnostic data if enabled.
5. Review related personalization options and turn off those you don’t need.

This limits data collection and personalization features.

5. Sign Out of Copilot

If you want to disconnect Copilot from your Microsoft account:

1. Open Copilot.
2. Click your profile icon.
3. Select Sign out.
4. Close the app.

Without an account, Copilot will not retain personalized memory tied to you.

6. Disable Copilot Completely (Optional)

If you prefer not to use Copilot at all:

1. Press Windows + I.
2. Go to Personalization > Taskbar.
3. Turn off the Copilot (Preview) toggle.

This removes Copilot from the taskbar.

Important Note About Copilot Memory

Copilot memory may be stored primarily in the cloud through your Microsoft account rather than entirely on your local device. Clearing app data alone may not remove account-level conversation history. For complete deletion, both local reset and Microsoft account privacy controls should be used.

Conclusion

If you want to delete Copilot memory in Windows 11, you can clear chat history, reset the app, remove Microsoft account activity data, or disable personalization features. Since Copilot relies heavily on cloud-based services, managing your Microsoft account privacy settings is the most effective way to remove stored interaction history.

By following the steps above, you can control how much information Copilot retains and ensure your Windows 11 experience aligns with your privacy preferences.
