In order to remove Copilot from Edge – but still have Edge you can use the information here for group policy purposes: https://learn.microsoft.com/en-us/DeployEdge/microsoft-edge-policies#newtabpagebingchatenabled
To do so with a registry key
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge]
“HubsSidebarEnabled”=dword:00000000
“NewTabPageBingChatEnabled”=dword:00000000
The first one disables the Side Copilot icon, the second the “Bing chat” in the middle of the start page.
You can also just download the reg file included below, click to have it download to you computer and click through the warning prompts to have it installed
