How to run a Twitch Live webinar with OBS

Open up your Microsoft Powerpoint slide, and from the top ribbon, click on "View" > Select "Reading View" (Reading view is deprecated in newer PowerPoint versions, if you are using a newer version, in that case, you have to resize your window in OBS, so it just shows the slide area). Make sure that your PowerPoint app is NOT minimized. 

Open your Open Broadcaster Software (OBS), go to "Sources", click on "+" icon and choose "Window Capture". Give it a name and from the next popup's "Window" menu, choose the "powerpoint.exe" app. Once done,  you will see the powerpoint slide in the preview area.

That's it!
