Invisiwind

Invisiwind (short for Invisible Window) is an application that allows you to hide certain windows when sharing your full screen.

So .. what does it do exactly?

I think this is best explained with a couple of screenshots I took during a Zoom meeting:

The screenshot on the left is what I see. The one on the right is what everyone else sees.

Using this tool, firefox and slack have been hidden so anyone watching the screenshare is unable to see those windows. However, I can continue to use them as usual on my side.

Note: this tool works with any app (MS Teams, Discord, OBS, etc) and not just Zoom.

So .. what does it do exactly? (for technical people)

Simple: The tool performs dll injection to SetWindowDisplayAffinity to WDA_EXCLUDEFROMCAPTURE.

How do I use it?

• Download and extract the generated zip bundle from here.
• Run Invisiwind.exe. You will now be dropped into a terminal.

Running it directly drops you into interactive mode. You can type help for more information.

You can also directly invoke it with commandline arguments. Type invisiwind --help for argument specification.

FAQ

I get a DLL error when trying to run Invisiwind.exe. How do I fix this?

You will need the Microsoft Visual C++ Redistributable for Visual Studio 2019. You can download it from here.

What OSes are supported?

Windows 10 v2004 or above. On previous versions of windows, a black screen is shown instead of hiding the window.

Do future instances of the application get automatically hidden?

No

Is it possible to see a preview of the screen on my side?

You can use something like OBS's Windowed projector.

Could I automatically hide windows using a hotkey?

Yes! In the zip bundle you'll find a AutoHotkey script that hides windows when you press Ctrl+J. Feel free to customize.
