Alexa just became more powerful on Windows 10. Amazon has previously brought Alexa with Windows, but wake words only worked on some computers. Now, Alexa can run in the background and listen to "Alexa" commands on any computer.
Amazon's voice assistant is more powerful than the Windows 10's built-in Cortana assistant. For example, it works with many more smart home devices. But until this update, Alexa did not wake words on each computer. Watchwords only worked on some computers – on others, you had to click the Alexa button to start talking. Now you can just say "Alexa" and start talking on any computer.
To get Alexa for Windows 10, install the Alexa app from Store. Start it and go through the installation process to log in with your Amazon account.
Give Alexa access to your microphone when prompted. Finally, you will be prompted to enable hands-free mode. In the hands-free mode, Alexa will listen in the background of the word "Alexa", just like an Amazon Echo does. This can use more battery power on a laptop. Click "Turn on handsfree" during the installation process to activate it.
By default, Alexa starts automatically when you start your computer. It must start and run in the background to listen to "Alexa" wake word.
Say "Alexa" aloud and start talking to using Alexa on your computer.
To turn off hands-free mode and save some battery power, open the Alexa app and click or tap the "Hands-free" button to the right of the blue Alexa button. You can still open the Alexa app and click the Alexa button to start talking to Alexa.
Alexa will also stop listening when you close the application. Resume Alexa to use it again.
