That's the full output?  Very strange.  On a clean W8 install I get 126
entries under that key, regardless whether I have full admin rights or
being admin running UAC-restricted, or running under a non-admin account.

Try this without admin rights:

  $ strace -o ls.trace /proc/registry/HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft
  $ grep 'stat_worker.*=' ls.trace > ls.stat.trace

and paste the content of ls.stat.trace into your reply.
