The answer in 30 seconds
Screen sharing can reveal notifications, filenames, browser tabs and conversations outside the material you intended to present. The safest setup depends on whether participants need one tab, one window or the entire desktop.
Prepare the material, silence private notifications, share one tab or window when that is sufficient, and confirm the preview before displaying sensitive information.
Examples to adapt
Share the presentation window and keep unrelated documents closed.
A browser tab may be enough; check whether audio also needs to be shared.
Agree on the scope and stop sharing before opening passwords or personal messages.
Follow the method
- 1Prepare the workspace
Close private tabs, documents and messaging windows; pause notifications where available.
- 2Choose the sharing scope
Select a tab or application window if the task does not require the entire screen.
- 3Inspect the preview
Check the selected surface, title and any visible names before confirming.
- 4Stop and recheck
End sharing when the task changes, then explicitly start a new share if a different item is needed.
A checklist to keep
Use these checks to record what you found. The grid supports a decision; it does not make one for you.
| Check | What to examine | Action |
|---|---|---|
| Material | What must participants see? | Define |
| Scope | Tab, window or desktop? | Choose |
| Private items | Are messages or names visible? | Close |
| Preview | Is the correct surface selected? | Check |
| Finish | Has sharing been stopped? | Confirm |

What to check
A full-desktop share can reveal pop-ups outside the presentation.
The exact tab, window and audio options vary by meeting app and device.
Participants may be able to capture what you show.
Common questions
Can I switch tabs safely while sharing?
Check which surface the meeting app is broadcasting; tab sharing and whole-screen sharing behave differently.
Does hiding a window remove it from a full-screen share?
Not necessarily. Confirm the participant view or stop sharing before handling private information.
