Okay, this one is kind of funny (Windows 11, but I ran into it when searching for an answer for OP, and chuckled):

Hello Alex P, welcome to Microsoft Q&A forum.

Thank you for sharing your experience. I understand how frustrating it feels when features you’ve opted out of keep showing up.

Copilot is now integrated into Windows and Microsoft Edge as part of the operating system design, so there isn’t a supported way to remove it completely. Even if you uninstall the app or hide the button, some components remain because they’re tied to system features and will return with updates.

Here's some steps you can try to partially reduce its presence:

• Uninstall the Copilot app: Go to Settings > Apps > Installed apps > Microsoft Copilot > Uninstall, or use PowerShell. This removes the app temporarily, but cumulative updates or the Microsoft Store can reinstall it.
• Hide the Copilot button and sidebar: Use Taskbar settings or apply Group Policy/Registry changes to turn it off. Keep in mind that updates may re-enable these settings.
• Disable Copilot in Microsoft Edge: Open Edge settings > Sidebar > Turn off Copilot. This is separate from the OS-level integration.

However, in the whole picture, there’s no supported method to permanently block Copilot. It’s treated as a protected system component and will reinstall with cumulative updates and Store auto-updates.

If you prefer an environment without these integrations, switching to Linux is a valid option.

Warm regards,
