In the next Windows 10 update, expected to arrive in September, Microsoft will allow voice assistants like Amazon's Alexa to activate on the lock screen
New changes coming later this year — Microsoft is opening up Windows 10 even further to third-party digital assistants.
Context & Ripple Effects
This is the next step in a two-year Microsoft-Amazon détente. It began with the Alexa–Cortana cross-invocation partnership, moved into hardware when HP, Asus, and Acer signed on to ship Alexa inside their Windows 10 PCs, and extended the other direction with Skype calls coming to Alexa devices.
The September update changes the terms of that trade: instead of Alexa living as an app behind the login, Microsoft is granting it a system-level surface — the lock screen — that until now belonged to Cortana. That matters because Microsoft had been building its own always-on assistant hardware play with HomeHub, and this concession signals it would rather host rivals' assistants than lose the PC as a voice entry point entirely.
First-order effects
- Amazon gets hands-free Alexa activation on hundreds of millions of Windows 10 machines without any wake-up click or unlock, turning every PC an OEM has already shipped with Alexa preloaded into a functional Echo competitor.
- Cortana loses its last exclusive real estate on Windows: the lock screen is now open to whichever assistant the user or PC maker prefers.
Second-order effects
- HP, Asus, Acer, and other OEMs gain a differentiator they can market — full voice access before login — which pressures holdout PC makers to strike their own assistant deals or explain why theirs is locked out.
- Microsoft is effectively trading assistant mindshare for services revenue: the same openness that lets Alexa in also keeps Skype, Office, and Xbox services reachable through Amazon's ecosystem, as the Skype-on-Alexa integration already demonstrated.
Third-order effects
- If the pattern holds, the operating system stops being an assistant moat: Google, Amazon, and Microsoft assistants converge on the same devices, and competition shifts from platform ownership to whoever owns the default invocation — a fight over the assistant distribution layer rather than the OS itself.
- The PC joins smart speakers as contested voice territory, meaning assistant makers must win per-device defaults across ecosystems they don't control, and regulators' attention to default-placement and preinstallation practices likely follows.
The trend: Voice assistants are being unbundled from their parent platforms, with operating systems opening system-level surfaces like the lock screen so rival assistants can compete on defaults rather than app installs.
