While you can use voice assistants like Alexa on Windows 10, they still play second fiddle to Cortana. You can't just talk to your computer -- you have to either click a button or use a keyboard shortcut. Thankfully, Microsoft might be a little more egalitarian in the future. Albacore, WalkingCat and others have discovered that Windows 10 test releases may offer deeper support for third-party voice assistants. You could activate apps with a hotword (including when your PC is locked), and possibly "replace" Cortana on a system level. In one test, Microsoft also separated the search text box and the "talk to Cortana" feature on the taskbar.
