Windows 10 Insider Preview Build 19631 Releases

2 min read

Microsoft has launched Windows 10 Insider Preview Build 19631 to continue to correct some problems. The beta version usually has many known problems, so it is not suitable for users who are pursuing stability. At the same time, frequent updates require a lot of reading and writing on the local hard disk.

We recommend interested users to test in a virtual machine. If it is a mechanical hard disk, it is not recommended to install and use the beta version directly on the physical machine.


Starting in February, Microsoft provides Hyper-V virtual machine functions for ARM64 architecture devices. Users can enable and deploy new virtual machines on such devices.

Starting today, Microsoft will provide Windows 10 VHDX disk images that have been created for such devices. Users can directly import disk images.

After importing, you can directly use the Windows 10 virtual machine without manual installation and deployment, which will save some time for ARM64 devices with lower performance.

Interested users can click here to download the VHDX disk image. Note that this effect is only supported on ARM64 devices and does not support the x64 hardware architecture.
