How to disable copilot icon in powerpoint enterprise

Question

↑ at the bottom corner I know the official microsoft help says I can uncheck the "copilot" box but this option does not exist anywhere in my powerpoint.

Answer 1

Your registry entry is correctly created, but this specific flag alone no longer disables the new Copilot bubble icon in the latest enterprise builds (Nov–Dec 2024 onward).

Add this registry entry.

Step 1 - Go to:

HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\ExperimentConfigs\ExternalFeatureOverrides\office

If the office folder does not exist, create it.

Step 2 - Add these two string values (REG_SZ):

A. Disable the Help Pane Host (Copilot UI container)

"Microsoft.Office.HelpPaneHost"="false"

B. Disable the new Copilot UI surface (additional trigger)

"Microsoft.Office.UnifiedCopilotUX"="false"

These two are actually what drive the bottom-right Copilot bubble in the latest builds — not the PowerPoint-specific experiment.

After adding them

• Close ALL Office apps
• Restart PowerPoint
• If the icon still appears → Restart Windows once (some builds cache UI components)

Answer 2

Thanks for sharing the details. Disable the Copilot “Experience Switch” by rolling back from the Microsoft “Connected Experiences” pipeline

This method works because Copilot in PowerPoint is delivered as a Connected Experience component, not a classic add-in. If you disable only the specific Connected Experience pipeline (not all), the Copilot UI stops loading, even if your admin has not disabled Copilot globally.

Step 1 - Close PowerPoint completely

Make sure all Office apps are closed.

Step 2 - Create this registry entry:

[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\ExperimentConfigs\ExternalFeatureOverrides\powerpoint]

"Microsoft.Office.PowerPoint.CopilotExperience"="false"

If the folder does not exist, create it manually.

Step 3 - Restart PowerPoint

The Copilot icon (bottom-right and ribbon entry) should be gone because the experimental experience ID is now explicitly disabled.

This is different from disabling Copilot, plugins, or privacy settings. You are specifically telling Office: “Do not load this experience bundle.”

See if this helps. If you need further assistance just let me know.
