ReactOS as the "open-source Windows" project working to implement binary compatibility for computer programs and drivers for Microsoft Windows now has experimental support for running on 64-bit ARM.

ReactOS has long catered to i586 and AMD64 while thanks to the work of an open-source contributor the past many months, ReactOS is now able to boot on ARM64.

ReactOS shared on X the milestone today of this experimental ARM64 support. The screenshot shown has the experimental ReactOS code booted as a QEMU virtual machine targeting an Apple ARM64 processor.

The ReactOS ARM64 build requires a UEFI compatible system with GICv2 or GICv3 enabled and can work on Armv8-A and newer.
