Found an old XP SP3 VM, here are the changes between XP SP3 and 2003 (2003 SP2, actually, that's the machine i mentioned earlier). Highlights: -CreateSystemThreads@8 +CreateSystemThreads@16 Definitely something changing here between versions! +IsProcess16Bit@0 So this is a 2003-only function? -PrivateSetDbgTag@8 -PrivateSetRipFlags@8 -QueryUserCounters@20 QueryUserCounters is mentioned here[1] -RegisterUserApiHook@8 +RegisterUserApiHook@4 Puzzling. -VRipOutput@0 -VTagOutput@0 So these mysterious functions didn't make it into Server 2003, but 7 has them? Weird. What do we do with all these functions? Keep all? What about functions that change their arguments? Not to mention that we probably have no prototypes for them (any of them; though i didn't check) in our headers.
