Microsoft is offering more and more support for the Arm64 chip architecture, despite some initial criticism and some potential setbacks in terms of how Windows 10 (OS) and the various apps will work on these processors. The latest Windows 10 Insider Preview Build 19559 for the Fast Ring update cycle adds Arm64 support to Microsoft's Hyper-V hypervisor for Windows 10 Pro and Enterprise users.

The reason why this is a big deal is that with Hyper-V being activated can yield higher performance from virtual machines on Windows. This is due to VMs running on a hypervisor that can run at a lower level than when running on top of another OS. Even if you don't usually use Virtual Machines, you may still want to use the Windows Sandbox feature. This feature a one-click Windows 10 VM that allows you to browse safely or download risky files without having it contaminating your computer.
