Your team meeting starts, you share the presentation, and someone spots the WeChat window at the edge of the screen — or worse, the notification with a message preview. Chat apps are the number one reason people need screen-share privacy, and the standard advice ("just close it") does not work when the conversation is why you are online.

Here is how to keep WeChat, WhatsApp, Telegram, Slack or any chat app out of your screen share on Windows.

Why chat windows keep appearing

Chat apps are designed to stay visible: they pop to the foreground on new messages, show previews in toasts, and keep their window open even when you switch away. When you share your desktop, every visible window goes into the stream. Minimizing helps only until a new message re-raises the window — and notifications can reveal message content by themselves.

What does not work

• Closing the app. You miss the conversation, and message previews keep arriving on your phone anyway.
• Do Not Disturb. It silences notifications but the chat window itself is still visible whenever it is on screen.
• Dragging the window to a second monitor. Fine until you accidentally share that monitor, or a message preview pops up on the shared one.
• Blur or green-screen filters. Virtual backgrounds hide your webcam feed, not the windows you share.

What actually works: capture exclusion

Windows has a built-in mechanism that lets a window flag itself as excluded from capture. An excluded window does not appear in any screen recording or share — Zoom, Teams, Meet, OBS — while it stays fully visible and interactive on your own monitor. The catch: only the app that owns the window can set that flag, and chat apps do not.

HideMyShare sets the flag on the chat app's behalf. You pick WeChat, WhatsApp, Telegram, QQ, Slack or any window, and it disappears from the shared stream — not blurred, not covered, gone from the capture — while you keep reading and replying 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 the preset for your chat app — WeChat, QQ, Telegram, Slack and more are built in — or pick the specific window from the list.
3. Start sharing your screen as usual in Zoom, Teams, Meet, DingTalk, Tencent Meeting or Feishu/Lark.

The protected window is now invisible to everyone watching. A chat window you open later is detected and re-protected automatically within about a second, and input method candidate bars are hidden too.

What viewers see

Nothing marks the spot. The shared view looks like a normal desktop without that window — other windows simply take up the space, exactly as if the chat app were not open. The person on the other side has no way to tell you hid something.

FAQ

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

Can I still use WeChat during the meeting while it is hidden? Yes. The window stays fully interactive on your screen — you can read and reply as usual, and only the shared stream excludes it.

Does this work with screen recordings, not just live meetings? Yes. The exclusion applies to all capture: live shares and OBS recordings or streams alike.

Does HideMyShare hide notification previews too? Notification banners are part of the chat window's presence and are excluded along with it; input method candidate bars are protected automatically as well.
