The resulting Windows USB install bypasses Microsoft Windows TPM, CPU, RAM, and storage requirements, so it should be bootable from most modern computers even if they don't meet those minimum requirements. The entire installation is stored within a dynamic .vhdx image file stored on an exFAT formatted USB device. This enables you to also store and boot other distributions and system tools while continuing to use your removable drive for traditional storage purposes.
