Thanks posting in microsoft community, voice activation can really streamline your workflow, so I understand the interest. First, “Hey Copilot” is currently rolling out to Windows 11 users via the Microsoft Store, specifically for those in the Windows Insider Program. It’s not officially available on Windows 10 yet. Second, while the wake-word feature isn’t supported, you can enable Copilot itself on Windows 10 by installing Build 19045.3754 (KB5032278) or newer, and enabling experimental flags. Third, to use Copilot Voice (once available), you’ll need a working microphone, but TPM isn’t required for basic functionality. Microsoft hasn’t announced a timeline for “Hey Copilot” on Windows 10, but they’ve confirmed plans to expand Copilot features to more users based on feedback. If this helps, please mark the answer as accepted so others can find it too.
Best,
Carl
