What operating system do you use?

I'm curious to see what operating systems everyone is using here! I currently dual boot Windows 11 and Ubuntu. I can't ditch Windows all together since there are programs I use that will not work on Ubuntu or any Linux distro. I could attempt to use them in Wine or a virtual machine but since I already dual boot with Windows there's really no reason to do this.

I got a new laptop last November and it has Windows 11. I thought it would take a long time to get used to it, but it was pretty simple once I got things set up the way I like them with the settings.

Basically Windows 11.
