Question about the Windows 10/11 Xbox App and console streaming

https://www.xbox.com/en-US/xbox-game-streaming/console-streaming Try that.

Thank you for replying - but that link is for mobile devices specifically, not Windows 10 devices, which is what the OP was asking about.

Currently, the Xbox Console Companion streaming still works on Windows 10. The reason OP was asking about the Xbox app on Windows 10 is because the Xbox Console Companion app is prompting users to install the Xbox app, which does not have streaming support.
I know that there is supposed to be a new Console Streaming app on Windows 10 later this year, but it is not available yet. I was just clarifying that for the OP and anyone else asking the same question about the new app, since I came here with the same question.

Console companion app is no longer supported like the rest of Windows 8

You can stream from the Xbox app built into Windows 10 and 11

Hello amramlinebarger, sorry to hear you're having trouble.

The Xbox Console Companion app is mainly for Windows 10 and allows you to stream your Xbox One to One X consoles on Windows 10. This app does not work with the Series X/S consoles though and the Xbox app is recommended for streaming to your PC if you're running Windows 11.

If you are running Windows 11 the only way we'd ask you to try installing the app is if you were having trouble with your Xbox games just to see if that would help.

I second the statement as well the aforementioned links are not addressing the question at hand. Which is how does one stream from their local CONSOLE to their Windows 10 PC in the "New Xbox App for Windows 10" which is replacing the "Xbox Console Companion"
app?

he is using windows 11, streaming from console can be done in the xbox app now, no need for the companion app.
