I have seen mixed reports on USB vs Bluetooth, but I can say for certain that in my case, when I plug my Switch Pro controller into my PC and then start up a game that uses it and/or steam, it causes windows to start behaving weird.

For instance Alt-tabbing is broken, and when you open the start menu, a pop-up keyboard keeps disappearing and re-appearing.

I saw there is a reddit post under the Steam Controller subreddit about this issue, but I do not believe it is completely linked to steam. I think something updated in Windows that conflicts with the Nintendo Switch Pro controller.

(I am using a Switch 1 Pro Controller)

    I followed up with the reddit thread.

    This user advises they reverted to a recent Windows update from 10/26/2026 and the issue was resolved, so this is a Windows issue.

    Hopefully it can be fixed soon! I have no idea where the right place to report this sort of thing is, and cannot post on reddit (and would prefer not to even if I could lol.)

    Solution / Workaround from reddit while we wait for the official Windows update to fix it.

    "In case someone still needs it here’s a solution that disables the game pad to keyboard mapping altogether, no uninstalling updates and no waiting for a fix.

    Run this in elevated command prompt and reboot (must be a single line):

    reg add “HKLM\SOFTWARE\Microsoft\Input\Settings\ControllerProcessor\ControllerToVKMapping” /v Enabled /t REG_DWORD /d 0 /f

    You can revert this later by finding the key name in regedit and deleting it."
