A quick look suggests that (w32-version) does this.
Results should be:
  (5 1 2600) ;; XP
  (5 2 3790) ;; XP 64bit, Server 2003, Server 2003 R2
  (6 0 6000) ;; Vista, Server 2008
  (6 1 7600) ;; Windows 7, Server 2008 R2
  (6 2 9200) ;; Windows 8, Server 2012

You can find the major and minor version numbers here:

For Vista and later the build number changes with service packs etc.
