Uninstall Mixer from XBox One X

You cant. It is part of the Xbox system software. Why may I ask did you want it uninstalled?

Hey there Paul0xBR,

Thanks for reaching out to the Forums for clarity on this feature. As posited by @GT Dex , this feature is currently integrated into the dashboard of the Xbox platform
and cannot be disabled until it is changed in a future update.

If you would like to suggest it's removal in a future update, I suggest going to our
insider's reddit and posting the idea there.

Thanks for reading!

Alguma maneira de desabilitar? Acho um aplicativo inútil que reduz o desempenho da dashboard e tenho uma sugestão, deveria ser nossa escolha se queremos ou não, ou até mesmo poderíamos desabilitar, enfim fica aqui meu apelo.

[Translation-Any way to disable? I find a useless app that reduces dashboard performance and I have a suggestion, it should be our choice whether we want it or not, or even could disable, finally stays here my appeal.]

Im confused Mixer and Facebook are 2 different things? Do you need to uninstall the Mixer app? If so just go to the app press the 3lined button and manage apps. Facebook?? Facebook was removed years ago from XBox so Im not sure there.

You can remove Mixer from your Xbox by simply going to my games and apps. After you go to Apps, you look for Mixer and click the share button. Once you see many options look for the uninstall button and you should be good to go.
