A PC equipped with advanced AI capabilities and Windows Copilot integration
Sorry to disappoint you but Microsoft is likely intentionally rolling out the new unified Copilot experience over the old one, with server-side redirects from the old URL to the new endpoint. Because the change is enforced by Microsoft and tied to your account/tenant rollout, there’s no supported way to stay on the old Copilot interface once the redirect hits your account. Any “bypass” would be temporary and unreliable at best.
