Reece 046b70d7bc [*] [Pre-Win8.1] Optimize for modern nt instead of windows vista synch in legacy path; yes, this is how windows 7 and vista synch is somewhat implemented.
...on apis that predate those kernel revisions. so, technically this might be able to run on xp.
[*] GetThreadCookie optimization for all platforms
