A Clean Screen Before You Share It: A Checklist
Notifications, thumbnails and ads have a way of showing up the moment you share your screen. This five-minute checklist covers the window you share, the alerts you silence and the browser feed you tidy first.

You click "Share screen," and a chat banner slides in. Or the browser tab behind your slides is still on the YouTube homepage, thumbnails and all. Nobody's fault, really. Screens are busy places, and we only notice how busy when other people are looking at them.
The fix doesn't take long. Five minutes before a call, a class presentation or a quick walkthrough for a colleague is enough to make your screen boring in the best way.
Why shared screens go wrong
Three things cause most of the surprises.
First, you share the whole screen when you only needed one window. Everything open behind it is now part of the show. A Microsoft Q&A thread on this exact problem says that with the entire screen shared, the Teams chat window sitting in the background can't be hidden, and the practical answer from the moderator was to share a specific window instead. It's a community thread, not official documentation, but the advice matches what most people learn the hard way.
Second, alerts. Messages, calendar reminders and app banners all draw on top of whatever you're showing.
Third, the browser. Your feed is built around what you watched yesterday, not around who's watching today. A recommended thumbnail or a video ad can appear on a homepage you opened for a completely different reason.
The five-minute checklist
Run through these in order. None of them needs special software.
- Share a window, not the desktop. In most meeting apps you choose between your entire screen and a single window. Pick the window. If you need two apps, share them one at a time. It's a little more clicking, and a lot less exposure.
- Silence alerts first. On Windows, Focus Assist can be set to "Alarms only" or "Priority only," and you can add an automatic rule for when you duplicate your display. In Teams, setting your status to Do not disturb silences Teams but not your other messaging apps, so close those too. This walkthrough from Neowin covers the Teams side step by step.
- Close chat panes and hide previews. If a message preview can't appear, nobody can read it.
- Open a fresh browser window with only what you need. Close the other tabs. Not because anyone will read tab titles, but because you'll stop worrying about them.
- Check the page you're about to show. Scroll it once yourself. If it has a feed, a sidebar or ads, decide now whether they belong in the room.
Step 5 is the one people skip, so it gets its own section.
The part nobody plans for: your feed
Sites like YouTube are designed to show you something every time you load them. That's fine when you're alone. In front of a team, a class or your family, you probably want more control over what appears.
There are a few ways to get it, and they stack.
Use a direct link. Open the exact video or page you plan to show, rather than the homepage. No homepage means no recommendations.
Reduce the clutter that does load. If the page you need has ads, a YouTube ad blocker can keep pre-roll videos and sponsored elements from interrupting a demo. Pair it with the tips in How to Reduce Digital Distractions During Your Workday if the same tab is also where your afternoon tends to drift.
Blur images you'd rather not display. Some people prefer faces and thumbnails covered by default when others might be looking, whether that's a meeting room, a shared family laptop or a train carriage. A blur tool does that at the page level, and you can reveal an image when you actually want to see it. Our guide to blurring YouTube thumbnails explains the options and the trade-offs.
None of these tools replaces a quick look at your own screen. Detection isn't perfect, and video blur in particular is still in beta in BOSLA AI. Treat them as a safety net, and do the five-minute check anyway.
Different rooms, same idea
The checklist adapts easily.
A work call. Window sharing, Do Not Disturb, a fresh browser window. That covers nearly everything.
A class or training session. Add a direct link to the material, and test your screen on the projector before people arrive. Sometimes the display mirrors differently than you expect.
A shared laptop at home. Here the browser matters most. Cover faces and thumbnails by default, and keep the ad blocker on so the page is quieter for whoever sits down next.
A quick screen share on the move. On a train or in a café, assume more people can see your screen than you intend. Blur on, notifications off.
A habit that takes thirty seconds
Once the checklist feels familiar, shrink it to a single pause before you hit Share: Which window? Which alerts? Which page? Three questions, thirty seconds.
Where BOSLA AI fits
BOSLA AI is a browser extension, currently in Beta, for Chrome, Edge and Brave. It works on YouTube, X and LinkedIn. Today it can block YouTube ads and blur faces, thumbnails and sensitive images on the page, all decided on your device. Blur is off by default, so you choose when it's on, and a popup shows what changed on each page, with a Restore option if you want something back.
If your screen is part of your work, it might save you one awkward moment. You can find the extension at boslaai.co, and see what it already does in what we've built so far.
Then share your window, take a breath, and carry on with your meeting.
