How to hide WhatsApp from a screen share on Windows

Use the WhatsApp desktop app, protect that window, and share your entire screen. WhatsApp stays fully readable in front of you while everyone watching your screen gets an opaque privacy screen where it sits. Nothing is blurred on your side, and nothing is closed.

If you use WhatsApp Web in a browser tab, there is an extra step that matters, and it is the thing most guides skip. Both paths are below.

Why the desktop app is the right answer here

Protection applies to a window. The WhatsApp desktop app is its own window, so it can be protected on its own and everything else on your screen carries on as normal.

WhatsApp Web is a tab inside your browser, and a tab is not a window. Protecting the browser covers the whole browser — every other tab with it. That is usually not what you want, since the browser is often the thing you are actually presenting.

There are two ways round it, and both are quick:

Install the WhatsApp desktop app from the Microsoft Store or whatsapp.com. Best option, and it is the one this page assumes.
Install WhatsApp Web as an app. In Chrome, open web.whatsapp.com, then the ⋮ menu → Cast, save and share → Install page as app. In Edge, ⋯ → Apps → Install this site as an app. It then opens in its own window, separate from your browsing, and behaves like the desktop app for this purpose.

The steps

Download Hushglass and run the installer. It installs for your user account only, so there is no administrator prompt.
Open WhatsApp — the desktop app, or WhatsApp Web in its own installed window. Open it before the next step, because the window list does not refresh by itself.
Open Hushglass. Windows appear under ACTIVE WINDOWS and STATUS, each starting as Not Protected. Click Refresh list if WhatsApp is missing.
Click the WhatsApp row, then click Protect. The STATUS cell becomes a green Protected chip.
Share your entire screen in Zoom, Meet, Teams or whatever you are using — not the WhatsApp window itself, and not a single window. Sharing the protected window directly hands its pixels straight to the meeting app, and nothing can intervene.

Ctrl+Shift+Q protects or unprotects whichever window you are working in, from anywhere. That is the one worth memorising, because messages arrive when they arrive.

What people watching actually see

An opaque privacy screen where WhatsApp is, carrying a small line naming the tool. Not a blur of your chats — a blur is still your content, and video compression does unpredictable things to blurred text. There is nothing in it to read.

You keep seeing every message, and you can still type replies. The window underneath receives your clicks and keystrokes normally.

Notifications are a separate problem

This is the part that catches people out, so it is worth being blunt: protecting the WhatsApp window does not stop WhatsApp notification banners. A banner is a different window, owned by the Windows notification system, and it is captured like anything else on screen.

Turn notifications off for the duration:

Windows 11: Settings → System → Notifications → Do not disturb.
Windows 10: Settings → System → Focus assist → Alarms only.

Doing both — protecting the window and silencing banners — is what actually keeps WhatsApp off a shared screen. One without the other leaves a gap.

How this differs from the blur extensions

Search for this and you will mostly find browser extensions that blur WhatsApp Web. They work, and they have a real advantage: they can blur one chat, one contact photo or one preview rather than the whole thing.

The cost is that they blur it for you too. A CSS blur applies to the page, and the page is what you are looking at, so you end up toggling it on and off — or reading blurred messages. They also apply only to WhatsApp Web in the browser that has the extension, not to the desktop app and not to anything else on your screen.

If you want the granularity and do not mind the toggling, an extension is a reasonable choice, and it is free. If you want to keep reading your chats normally while nobody else can, that is a different mechanism. We wrote up the comparison in why blurring WhatsApp hides it from you too.

Check it before you rely on it

Once, with nothing sensitive open:

Start a meeting on your own and join it from your phone.
Protect the WhatsApp window and share your entire screen.
Look at the phone, not at the meeting app’s preview on your PC. Your own machine is the one place the result is guaranteed to look right whether or not it is.

If it is not working

They can still read the chats — you shared the WhatsApp window itself, or a browser tab containing WhatsApp Web, rather than sharing your screen.
The whole browser went dark for viewers — you protected the browser window while WhatsApp Web was a tab inside it. Install WhatsApp Web as an app, or use the desktop app.
WhatsApp is not in the list — click Refresh list.
A message banner still appeared — that is the notification system, not the window. See above.
A second window would not protect — the free tier holds one at a time.

Windows 10 version 2004 or later. Free for one protected window, which is enough for exactly this job.

Frequently asked questions

Does this hide WhatsApp notifications as well as the window?

No. A WhatsApp notification banner is a separate window owned by the Windows notification system, not part of the WhatsApp window you protected, so it is captured like anything else on screen. Turn on Do not disturb on Windows 11, or Focus assist on Windows 10, before the call.

Can I protect just one conversation instead of the whole app?

No. Protection applies to whole windows, so it covers the entire WhatsApp window or none of it. If you need one chat covered while others stay visible, a browser extension that blurs individual elements is closer to what you want — with the trade-off that it blurs them for you as well.

Will WhatsApp itself know, or show the other person anything?

No. Nothing about this touches WhatsApp, its servers or the conversation. It changes only what your own computer puts into a screen capture, so the people you are chatting with see nothing different and no message or status is sent anywhere.

Does it work with WhatsApp Web pinned as a Chrome app or shortcut?

Yes, and better than an ordinary tab. Installing WhatsApp Web as an app — Chrome's "Install page as app", or Edge's "Install this site as an app" — gives it its own window rather than a tab inside your browser, and a window is what protection applies to.

Is my chat history or message content read by any of this?

No. Nothing about the content of the window is read, transmitted or stored. The window is marked so that screen capture skips it; what is inside it is never inspected.
