You are about to share your screen in a meeting. Your chat window is still open, right next to the document you are presenting. Closing it means losing the conversation. Leaving it open means everyone sees it.

Here is how to hide a private window from a screen share on Windows, in any meeting app.

Why the chat window shows up at all

Zoom, Microsoft Teams, and Google Meet share whatever you point them at. If you share your entire desktop, every visible window goes into the stream — including personal chats, password managers, and notification popups.

Minimizing a window only removes it from the visible desktop. Alt-Tab still shows it, notification banners still pop over your presentation, and one accidental click on "share desktop instead of window" undoes everything.

What does not work

• Closing the app. You lose the conversation, and messages pile up unseen.
• Do Not Disturb. It hides notification banners, but the chat window itself is still visible whenever it is on screen.
• Moving the window off-screen. Most meeting apps capture the full desktop surface; parts of the window can still render into the share, and dragging it back exposes it instantly.
• A second monitor. Safer in practice, but you still have to share the right screen, and chat previews on the primary screen can leak.

What actually works: Windows capture exclusion

Modern Windows has a built-in mechanism for exactly this problem: an app window can flag itself as excluded from capture. When that flag is set, the window does not appear in any screen recording or share — not in Zoom, not in Teams, not in Google Meet, not in OBS — while it stays fully visible on your own monitor.

The catch: the flag can only be set by the application that owns the window. You cannot mark someone else's window as excluded; the chat app itself has to do it, and chat apps don't.

That is the gap HideMyShare fills. It marks the window you choose as capture-excluded on the chat app's behalf, so the window simply disappears from the shared stream while you keep reading and typing normally.

Step by step (about 30 seconds)

1. Install HideMyShare and open it before the meeting (Windows 10 version 2004 or later, Windows 11 supported).
2. Click an app preset — WeChat, QQ, Telegram, Slack and more — or pick a specific window from the list.
3. Start sharing your screen in Zoom, Teams, or Meet as usual.

The protected window is now invisible to meeting attendees. A window you reopen later is detected and protected automatically within about a second, and input method candidate bars (the text suggestions above your keyboard input) are protected too — a detail most people only notice after it has leaked.

Does it work in every meeting app?

Yes — as long as the app shares through the normal Windows capture path, which includes Zoom, Microsoft Teams, Google Meet, Webex, DingTalk, Tencent Meeting, Feishu/Lark, and OBS recordings or streams. The exclusion is enforced by the operating system, so each app does not need individual support.

Two things it is not: it does not blur the window (it removes it entirely from the capture), and it does not hide it from someone looking at your physical screen. It protects the share, not the room you sit in.

FAQ

Does the other side see an empty gap where my window was? No. The other windows simply take up the space, exactly as if the window were not there.

Can I still use the hidden window during the meeting? Yes. It stays fully interactive on your screen. You can read and reply as usual.

Does this work on macOS? The capture-exclusion approach used here is Windows-specific. HideMyShare currently supports Windows 10 (2004+) and Windows 11.

Will participants know I hid something? The shared view looks like a normal desktop without that window. Nothing marks the spot.
