Actually you're only partially correct. Patches that do not enter registry
changes are not found by the baseline tool or hfnetchk even though they are
properly installed. Some good examples of this are some SQL patches.
Microsoft has a paper on this on their support site. Another possibility
that you may be running into is that most(not all) patches can be
overwritten by other patches or service packs which then requires you to go
through the patch process all over again.

I've never heard about this, does anybody else care to comment on MS
patches
not actually installing the files? From what I understood, in cases where
the MS tools returned a vuln you thought you've covered, it's because they
require a work around and not a patch [e.g. the hfnetchk warning]. The
only
case I've seen a installed patch fail a check was when software I'd since
installed regressed a file.

That means those updates didn't apply properly. What MBSA, and the HFNetChk
tools it's a limited version of, do is actually check if the files updated
by the patch are at the proper versions. Sometimes MS patches don't apply
right, so even though you've downloaded and installed it, and Windows
Update, which just checks if the registry says the patch is installed, says
it's installed, it's not actually installed. It's unfortunate that MS
patches often don't actually patch..

The only tool that I know of that almost does all of that is the MS
Baseline
Security Analyzer. It's a gui tool that scans your system and tells you
what
potential holes you have and tells you what patches you are missing. I have
had some problems with it as far as the patches go because it will tell me
that I'm missing updates that I know that I've already downloaded and
installed.
