And so it does, but you'll notice from the MSDN docs that the \\?
syntax must be supplied as a Unicode string, which os.listdir
will do if you pass it a Python unicode object and not otherwise:

import os
os.listdir(u"\\\\?\\c:\\users")

# and consequently

for p, ds, fs in os.walk(u"\\\\?\\c:\\users"):
  print p
