MMSUPPORT_FULL

The MMSUPPORT_FULL evolved from splitting the MMSUPPORT structure into parts for the 1607 release of Windows 10.

Variability

As an internal structure with little, if any, visibility outside the kernel, the MMSUPPORT_FULL varies between builds.

Version Size (x86) Size (x64)
1607 0x88 0x0108
1703 to 1709 0x8C 0x0110
1803 0x90 0x0110

Layout

These sizes, and the names, offsets and types in the tables that follow, are from Microsoft’s symbol files for the kernel.
