A Belmarc Advisor Profile shows that I need to reinstall eight(8)
updates for my Microsoft Windows 98 System. They are Win98.SP1:
UPD168115 and UPD238453; Win98: UPD245729; UPD256015; UPD259728;
UPD273991; UPD314147; UPDQ823559.
I have the original installation disk but that won't necessarily
include the  exact items. I an a novice at computer technology but can
follow clear instructions at the appropriate level.

As the comment below from dreamboat-ga correctly indicates, the best
place to look for supported updates to a Microsoft operating system is
the Windows Update website at http://windowsupdate.microsoft.com .
When you navigate to that URL, an ActiveX module from Microsoft will
run to help you analyze your specific installation of Windows, and
will advise you what updates, if any, need to be downloaded and
installed.

However, if you run into any problems using the Windows Update
service, or wish to learn more about the updates before installing
them, you can also read the specific advisories released by Microsoft
by looking up each of those update numbers at the
http://support.microsoft.com website. Here are the direct links to
each of the relevant updates identified by Belarc Advisor:

You may need to have your original installation disks handy during the
installation of these patches, if your installation does not already
include all of the necessary features involved in the patch. Usually,
these types of patches can be applied seamlessly with minimal user
interaction when you use the Windows Update service, so I wholly
recommend giving that website (http://windowsupdate.microsoft.com ) a
visit before using the direct links that I have provided above. If you
do need to download the patches manually using the links I have
provided, download them to a location where you can easily find them
again, as you will need to run each one after you have downloaded them
in order to install them.

Please let me know if you run into any problems applying these
patches, by using the "Request Clarification" button above.

I hope that this helps,

I rate this answer five stars even though I am not skilled to put it
to the test, to obtain the desired results. The Researcher writes very
clearly. I appreciate the thoroughness and time given to my question.
I do not tip; I haven't income to allow it. I do hope the $40 is
acceptable with the Reasearcher. Thank you,aht-ga. I am consulting a
technician to determine which of these updates are necessary and to
install only those, as aht-ga advises. As I better learn how price my
question I should be able to arrive at figure that will cover both the
answer and a tip. Thanks.

Those updates aren't on the original CD, at least not to my knowledge.
They should be found here, tho:  http://windowsupdate.microsoft.com/
