Windows 11. Because my PC comes with a 12th gen Intel processor, and from what I've heard Windows 10 doesn't really know how to address the P and E cores properly. I've tried both Linux and macOS, they're both not my cup of tea, and I keep finding myself crawling back to Windows.
On my old laptop, I was using Windows 10.
