Does Windows show which apps are using your microphone?
Yes. It’s a built-in privacy feature, it has nothing to do with what's on your screen, and it doesn't matter whether the app is sharing the microphone politely or not.
It's a privacy feature, and it works
Windows added a microphone activity indicator for an ordinary reason: people want to know when something is listening. It's the same instinct behind the camera light on a laptop — visible, hard to miss, and not tied to any particular app's cooperation. Open Settings → Privacy & security → Microphone and there's a plain list of what has used it recently. It doesn't ask the app's permission to report itself, and it doesn't check whether anything is being shared on screen. It just watches whether the microphone is on.
Why that catches more than people expect
The instinct is to assume an app being "polite" about sharing the microphone with other software — rather than hogging it for itself — would somehow stay off the list. It doesn't work that way. Windows tracks every app with the microphone open, politely-shared or not, and politely-shared is how almost every ordinary app actually uses it. There's no quieter way to turn the microphone on and avoid it. If an app has your microphone open at all, it's on the list.
During a live video-call interview, that means any interview-assistant tool capturing your own voice — which is most of them, since that's normally the only way to hear you at all — is visible there for as long as the call runs. Not on the shared screen. In a completely separate place someone would have to know to check, but a real one.
What actually gets an app off the list
Not a setting, not a permission, not a lower-privilege capture mode — the absence of a capture session on that machine at all. CueStream's Android companion app captures your voice on a phone instead, mixed with the interviewer's voice coming out of your own speakers, and streams that single audio feed to the desktop over your own Wi-Fi. The desktop never opens the microphone. There's no session for the indicator to find, for the same reason an empty room has no camera light on — nothing is running that would trigger one. The full mechanism, including what it doesn't solve, is on the microphone privacy indicator page.
Check it, don't take it on faith
This is a two-minute test and it's worth running before a real call. Open Settings → Privacy & security → Microphone. Start an ordinary CueStream session and watch it show up in recent activity while it runs. Stop it, turn on "Use Android phone as microphone," pair the companion app, and start again — watch it not show up. That's the entire claim, verifiable on your own machine in the time it takes to read this paragraph.
Where exactly does Windows show this?
Settings → Privacy & security → Microphone, under recent activity, plus a live indicator while a session is active. It’s built into Windows 10 and 11 for every user, not something an employer has to separately install.
Does keeping the CueStream answer window off a shared screen also hide this?
No — they’re unrelated. That feature changes what a screen-sharing or recording app receives. The microphone indicator has nothing to do with the screen; it just watches whether the microphone is turned on.
Is this specific to CueStream, or does every app that uses your mic show up this way?
Every app. Zoom, Teams, Discord, a voice-typing tool, anything that opens the microphone shows up the same way while it’s recording. The interesting question for an interview isn’t whether the indicator exists — it’s whether the interview-assistant app you’re running is one of the things using the mic.
