NtGetTickCount
Other → NTSTATUS
NtGetTickCount is a Windows NT kernel system call, in the Other category, returning NTSTATUS. Its syscall number is not the same on every Windows release: across the 16 version-and-architecture pairs recorded here it takes 5 distinct values, from 0x0034 to 0x004C.
The number is an index into the system service table of one particular build, not a stable identifier, so it is not portable between Windows versions. The table below gives the value recorded for each.
