How is it that I get two totally different security reports from MS
Update and from MSBSA? I just don't understand this! I don't know
which one to trust and to go by.

Here are the results form MS Update:

High Priority(0)
                                      Software, Optional(0)
Hardware, Optional (1)
No high -priority updates for your computer are available.
----------------------------------------------------------------------------
Here are the results form Microsoft Baseline Security Analysis:

Office Updates 1 update is missing.
SQL 1 critical security updates are missing. 1 products are
using a service pack not at the latest version or have other Server/MSDE
     warnings.
MSXML 1 products are using a service pack not at the latest
version or have other warnings.
Windows 1 security updates could not be confirmed.
