# TurnOffWindowsCopilot: disabling Copilot in Windows by policy

**Short answer:** TurnOffWindowsCopilot is the policy that disables the Copilot sidebar in Windows, and a second value hides its taskbar button. This tweak sets both. In the registry it sets TurnOffWindowsCopilot to 1 under HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsCopilot, and 1 more value.

## In the app

- Switch: Disable Windows Copilot (Windows, Pro, Standard)
- Undo: Partial. Switching it off allows Copilot again through a Windows policy instead of removing the policy, so Windows may show the setting as managed by your organization.
- Catalog row: https://frozentweaks.com/tweaks#t-1111

## What it does

TurnOffWindowsCopilot is the policy that disables the Copilot sidebar in Windows, and a second value hides its taskbar button. This tweak sets both.

In the app the switch is called "Disable Windows Copilot", described there as: Hides/blocks Copilot via policy and taskbar flag (Win10/11 latest).

## When it helps

- Removing the Copilot button and keeping the Win + C shortcut from opening it.

## When it hurts

- Newer Windows 11 versions ship Copilot as a regular app that this policy does not remove, so the result depends on your version.
- Switching the tweak off sets standard values, which may not be exactly what you had.

## What it writes

Read from the app's source. "Switching it off" is what the app writes when you turn the tweak off again.

Registry values:

| Key | Value | With the tweak | Switching it off |
| --- | --- | --- | --- |
| `HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsCopilot` | `TurnOffWindowsCopilot` | `1` | 0 |
| `HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced` | `TaskbarCopilot` | `0` | 1 |

Source: Tweaks/tweaks_copilot_teams.hpp in the app's source, app 2.0.0, checked 2026-10-08.

## The same change by hand

Run in a Command Prompt opened as administrator. Make a restore point first.

```bat
reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsCopilot" /v "TurnOffWindowsCopilot" /t REG_DWORD /d 1 /f
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /v "TaskbarCopilot" /t REG_DWORD /d 0 /f
```

Put it back:

```bat
reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsCopilot" /v "TurnOffWindowsCopilot" /t REG_DWORD /d 0 /f
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /v "TaskbarCopilot" /t REG_DWORD /d 1 /f
```

See what it is set to now:

```bat
reg query "HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsCopilot" /v "TurnOffWindowsCopilot"
```

## How to undo it

Switch the tweak off in Frozen Tweaks. It writes TurnOffWindowsCopilot back to 0, TaskbarCopilot back to 1. Switching it off allows Copilot again through a Windows policy instead of removing the policy, so Windows may show the setting as managed by your organization.

## Verdict

Harmless. On recent builds, uninstalling the Copilot app is the more reliable route.
