ReactOS, the open source project aiming to recreate Windows NT, has reached a new milestone: booting on ARM64. The ReactOS team cautioned that the build was "still in an experimental state," while encouraging users to try it. Screenshots show the project running on ARM64 (via QEMU) and on a Raspberry Pi 5. ReactOS recently celebrated 30 years since the first commit to the project's source tree, with the current development targeting Windows Server 2003 compatibility. We last covered it in 2025 and came away impressed by its faithful recreation of the Windows golden age. Unlike WINE, which layers Windows applications support onto Linux, ReactOS recreates the NT kernel from scratch, right down to driver support. The ARM64 port is very much a proof of concept - there's precious little that you can actually do with it yet. But watching that familiar Windows desktop appear on the hardware is genuinely joyful, and dismissing it as an "it boots" milestone would be a disservice.…
