Appendix H. Service Packs
Nothing's
perfectespecially
Microsoft's security record. With years passing
between major Windows releases, the only way to deal with new
security problems and accommodate new technology that comes along, is
to regularly run Windows Update. Or better yet, get everything
packaged in Microsoft's Service Packs, which seem to
be issued roughly every two years. Service Packs gather up all the
important bug fixes that you may have missed, add additional security
tools and features, and tie up any loose ends. You
don't typically get many new toys to play with, but
there can be a few nice surprises lying in wait, from better wireless
networking support to an easier to configure firewalltwo
notable improvements included in Service Pack 2 (SP2).No matter how often you run Windows Update, it's
important to install Service Packs when they become
availablethey'll add still more fixes and
tools. Just remember that anything that mucks with the inner workings
of your operating system should be approached with care. Nine times
out of ten, installing a Service Pack is safe and easybut you
don't want to be that unlucky tenth person.
We'll show you what traps to avoid in the process
and what precautions to take.In this appendix, we'll look at both of the Service
Packs released at the time of this writingService Pack 1
(which by this point you probably have, since it was preloaded on
many PCs sold after Fall 2002) and the more recent Service Pack 2.
While there's no way of knowing if the future holds
a Service Pack 3 and 4 between now and the launch of
XP's successor, the same advice will apply if and
when the time comes to install them on your machine.
