Completely disable guide button to open steam window and also big picture mode! HELP!

[WilliamLeGod]

Guys. I've been having this issue for the last 10 years straight and now I just can't take it anymore. Please help me disable guide button to open Big screen mod, please I'm begging 😦
I've tried many methods such as disable guide button in controller section, try turning on xbox game bar in windows 11 but when I press the guide button in steam, it forces xbox game bar off and then open big pic mode. I also try to use the DEFINE LAYOUT method but the option is MISSING??? I'm using xbox controller connected via wireless dougle.
Appreciate any help!

Thanks bro. This is so annoying :(

I ended-up here looking for a solution and didn't find an easy one, so I have made a Powershell script to remove all references to the Guide button assignment.

It backs-up your current Steam config before opening it and deleting all 'guide:xx' refences, and then saves it (overwrites current config), thus solving the guide button problem once and for all.

Full details on what it is and how it works are on Github, where the code can be see before using it.

Hope it helps! 🍻
