VMMCall VMM_GetSystemInitState
mov [InitState], eax
Retrieves the current system initialization state. Uses EAX, ECX, Flags.
The following table identifies initialization milestones and return values for VMM_GetSystemInitState. Milestones are listed in the table in chronological order. When a milestone completes, this service returns the value (one of the values) listed to the right of the milestone. The first value is returned if the first milestone has not been completed.

| SYS_VM_TERMINATE is broadcast | SYSSTATE_PRESYSTEMEXIT (E0000000h) |
| SYSTEM_EXIT is broadcast | SYSSTATE_PRESYSTEMEXIT2 (E4000000h) |
| SYSTEM_EXIT2 is broadcast | SYSSTATE_PRESYSCRITEXIT (F0000000h) |

| REBOOT_PROCESSOR is broadcast (See Reboot_Processor function) | SYSSTATE_PREREBOOTCPU (0xFFFFFF00) |
VMM.H contains the above definitions.
Future versions of Windows may have additional initialization states with values between the ones defined here, which implies that you should use a relational comparison to test the initialized state. Currently, this service returns zero in ECX, but additional information may be returned in this register in the future.
