I have a Keychron K3 Pro keyboard that can be programmed with VIA and I’m more than happy with it.

My mouse is a VAXEE Outset Wireless. This doesn’t need any software to change DPI / polling rate etc. All of it can be done by pressing buttons on the underside of the mouse. It works very reliably.

I’ll switch my windows drive to the LTSC IoT version, when this happens. The only reason I have dual boot is for a fallback, if some games make trouble. For example for whatever reason BG3 multiplayer freezes randomly on linux. Single player is fine though. So until I got that sorted out I can fall back to windows. But when even the LTSC support runs out, then that’s it completely for me.
