This seems to work best:

A wrapper that allows XP/2003 to run some newer NT6 stuff that BWC kernel for win2k can also run, I believe, like Blender 2.79b.
There are a few others, like Dibya's ExtendedXP, One-Core-API, and BWC's Extend Kit for XP/2003 but they are buggy, not very advanced and/or contain non-redistributables.
