sysinternal disk2vhdx

Disk2vhd only converts from a physical disk to a VHD; it does not provide a reverse (VHD/VHDX back to physical disk) function.

To go from a VHDX back to a native hard drive, supported tooling in the provided context is:

• Use Hyper‑V tools to manipulate the VHD/VHDX format (for example, Convert-VHD to change between .vhd and .vhdx formats or types), then
• Deploy or apply that VHDX image to physical hardware using standard Windows deployment methods (for example, treating the VHDX as an image container and applying it to a disk, or using it for native boot as described in the VHDX native boot documentation).

There is no single Sysinternals utility in the context that performs an automated “VHDX → physical disk” clone in the same way Disk2vhd does for “physical → VHD”.
