If you could show us examples, we might even be able to look into
this problem, *if* it is a problem.  I just tried the following on
Windows 7 as an UAC-restricted admin:

  $ ls -l /proc/registry/HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/ | wc -l
  149
  $ regtool list /HKLM/SOFTWARE/Microsoft | wc -l
  149
  $ reg query HKLM\\SOFTWARE\\Microsoft | wc -l
  149   <--- This is wrong!  It only shows 148 entries, the first line of
             output is empty.

And this is under a fully enabled admin shell:

  $ ls -l /proc/registry/HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/ | wc -l
  148
  $ regtool list /HKLM/SOFTWARE/Microsoft | wc -l
  148
  $ reg query HKLM\\SOFTWARE\\Microsoft | wc -l
  149   <--- Actually 148, as above.

The difference is an entry called "AudioCompressionManager", which
is only visible when running UAC-restricted.  Note that this entry
is not visible when using the Windows reg tool at all, and it's also
invisible in regedit.

Now, if you could give us some details from your side, we might be
able to see a pattern.
