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, and when it hurts
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
Exactly what the switch changes, read from the app's source. Switching it off is what the app writes when you turn the tweak off again.
