Windows 11 can even run natively on a Raspberry Pi 4
Windows 11 does not officially support the Raspberry Pi 4, but the new OS will currently run on the popular single-board computer (SBC). As it stands, the Windows 11 Insider Preview will run on anything that can boot it, meaning that Microsoft is yet to apply its changing processor requirements.
Surprisingly, Windows 11 run smoothly on the Raspberry Pi 4, even at this stage in the operating system's development. Additionally, the Raspberry Pi 4 only has a Broadcom BCM2711, an SoC that has four ARM Cortex-A72 cores that can reach 1.5 GHz. The BCM2711 also has 1 MB of L2 cache and has been demonstrated running on 8 GB of RAM. Theoretically, Windows 11 could run on a Raspberry Pi 4 with 2 GB or 4 GB of RAM, although we would expect to see a performance drop off.
Apparently, Windows 11 runs better on the SBC than Windows 10 does, too. We should stress that this is the ARM64 version of Microsoft's latest OS, which the company has distributed to devices like the Surface Pro X. Leepspvideo has provided an overview of how Windows 11 runs on a Raspberry Pi 4, which you can watch below. Additionally, he has published a video on installing Windows 11 on a Raspberry Pi 4, or any of its derivatives, including the Raspberry Pi 400.
