2 Xbox One controllers on PC

• To configure the Xbox Elite Wireless Controller Series 2, get the Windows 10 May 2019 Update (or later) and make sure your PC has the latest fixes.
  
  See how to get updates.
• The Xbox Accessories app won’t detect your controller if you’re using Bluetooth to connect to your PC. Connect your controller using Xbox Wireless, or plug the included USB-C cable into the back of the Xbox Elite Wireless Controller Series 2 and plug the
  other end into your PC. For more info, see

xbox elite controller 2, Microsoft Xbox One Wireless Adapter (this big one, not the tiny flashdrive sized one). and PC. or are you asking specs to the PC?

EDIT: Yes to everything being updated.

I want to play an Xbox 360 game with split-screen on my Xbox One X. For the primary account signed in, I can use the wireless Xbox One controller that came with my Xbox One X. But I would like a guest to be able to use one of my Xbox 360 controllers, as
I only have one Xbox One controller. I have a 3rd party (USB) wired and other official wireless Xbox 360 controllers.

I tried using both of these Xbox 360 controllers to try and connect to the Xbox One X using the sync feature but none of them connected. The lights on the Xbox 360 controllers just flash infinitely.

I did hear that Xbox 360 controllers are not compatible with Xbox One’s but does this apply to the Xbox One X as well?

I also tried using the stream Xbox → Windows 10 feature and plugged in my 3rd party USB Xbox 360 controller to my PC which did connect to my Xbox though streaming, however it kept overriding my Xbox One controller by connecting as player 1. I
need it so one of them is player 1 and the other as player 2 so two of us can play split screen.

Is this at all possible, using an Xbox One and Xbox 360 controller?

Thanks.

Maybe you can achieve this using console streaming to PC and connecting both controller to your PC, so the PC have 2 different controllers plugged in and you can use with 2 different player.

As additional info, every Xbox One wireless controller can work as a wired one using a simple USB cable.

I have a 360 controller that's been working fine on my PC for the past 2 years. I recently got an xbox one controller and it's been disconnecting/reconnecting at random times.

Hello, I have pc with windows 10.

I would like to know, if I buy Read Dead Redemption 2 on xbox store with my pc, will I be able to play it with an xbox controller ?

Be aware that if you buy a Xbox Game through the Xbox Marketplace, that you get the Xbox console version of the game.

Red Dead Redemption 2 is (not yet) available on PC. So the only way to play it on PC is to stream it from a Xbox One in your home network to the Xbox App on your PC.

But you can use a controller to play the game. In fact, you'll have to use a controller, as you play the game on the console that way.
