Other updates for Insiders

ARM64 VHDX available for download

Back in February with [Build 19559], we added the ability to install Hyper-V on ARM64 devices such as the Surface Pro X running the Enterprise or Pro editions of Windows 10. Today, we are offering the ARM64 VHDX for Windows 10 Insider Preview Build 19624, so that Insiders can run Windows 10 as a guest OS in Hyper-V. You can download the VHDX here. We will regularly release updated VHDX downloads for newer Insider Preview builds going forward.

Note: Hyper-V on Windows 10 ARM64 devices only works on Windows 10 Insider Preview Builds 19559 and above. Nested virtualization is not supported.
