All security patches are signed. Once you download the file, right click
on it and view properties, you should see a tab for digital signatures.

If you expand the signed package, the files within the patch won't have a
digital signatures tab, however, after you install it, run sigverif.exe and
you can verify that all the files are now signed (the CAT file registers
all the files as signed)

What gave you the error messages below? Had you enabled a security policy
on your system to "not install unsigned drivers"? I've found that this
will usually cause problems as it views the files as unsigned before they
are registered via the CAT file.
