The architectures of Windows 11 and the Raspberry Pi aren’t the same, meaning you’ll the Raspberry Pi won’t natively support Windows 11. Despite Windows conventionally needing an x86/x64 processor, Windows 11 is compatible with the ARM architecture.
You’ll need specialized tools and good know-how to get Windows up and running on a Raspberry Pi. But it’s not impossible. However, the more significant problem is that the Raspberry Pi lacks the sheer processing power you need to run Windows 11. So, even when you install Windows, it would be best to keep your expectations to a minimum.
