Dell Support 5.0 vs. Dell’s Download/Drivers pages

Hi,

I just got a new D3000 (July/05).  “Dell Support” version 5.0.0.630 software came with the computer and seems to have been doing “its thing”.  When I run the “Security” and “Maintenance” channels, the software lets me know that I have all the current updates.   (I have also spent the last few days getting all Windows Updates, Office Updates, and Norton updates, so all that should be OK now too).

However, when I go to the following Dell page and enter my computer’s “Service Tag”, it shows many updates (and I think my computer might need some of these right now, according to how they are described).

Should I expect the Dell Support v 5.0.0.630 to have already gathered the updates for my computer that are listed at http://support.dell.com/support/downloads/ ?  …or do I need to keep track of both ways to get updates?

Also, one of the updates listed on Dell's download page, for my Service Tag, is for

“Dell Desktop System Software Utility

Release Title: System Utilities: Dell Desktop System Software, Utility, Windows 2000, Windows XP, Windows XP x64, Multi Language, Multi System, v.1.7.0, A04

Release Date: 06/21/2005

Description: Desktop System Software (DSS) is a utility that provides critical updates and patches for your operating system.

DSS automatically detects your computer and operating system and installs the updates appropriate for your configuration.”… “R96610.EXE”

Is this an upgrade to the “Dell Support” version 5.0.0.630 that is already on my computer?  Why such an odd version number, if it is (“v.1.7.0, A04”).  If this is a completely different type of software, then how does it vary from the Dell Support 5.0.x? 

BTW… am I on the right sub-board?  I didn’t see any reference to Dell Support software 5.0x in the faq or other messages… only up to version 3.0.  The Dell Support software seems useful, but trying to figure out how it fits into all the other things with similar names and download processes is baffling.  I have no idea what more (if anything) I need to do to ensure that all my drivers and software are as up to date as possible,… nor do I understand why some stuff on the download page looks like it needs to be added to my computer when the Dell Support software says that everything is already up to date.

Thank you.
