Without a true multi-version driver, your MVCI might work perfectly on your shop’s old Win7 32-bit programming station but fail entirely on the new Win11 64-bit service laptop.
| Strategy | Description | |----------|-------------| | | #if (NTDDI_VERSION >= NTDDI_WIN10) for OS-specific APIs | | Runtime OS version checks | RtlGetVersion() to adjust behavior | | Separate binaries per OS | Different INF + sys per OS family | | Unified binary with dynamic dispatch | One binary uses function pointers for KMDF/WDM differences | mvci driver for x32 64 os multi version
“I want you to ship by Friday.”
However, due to increasing security requirements (mandatory signing, HVCI compliance, 32-bit deprecation), future iterations must evolve toward a more modular, user-mode-first design while maintaining backward compatibility for critical deployments. Without a true multi-version driver, your MVCI might
