1.5. Windows Service Packs
Service Packs are infrequent
but major updates to Windows XP, and are primarily designed to squash
bugs, sew up security holes, and add new features to the operating
system.The first, Service Pack 1, is undoubtedly already
installed on your computer, either via Windows Update or because you
bought your computer in the last two years. It may be a while before
its follow-up, Service Pack 2, released in August 2004, is
as ubiquitous. Microsoft admits that the adoption rate has been slow,
no doubt because SP2 is hugeand because it introduces some new
problems.Still, it's important to install these Service
Packs. Just keep in mind that doing so is a major update to your
system. Always back up your important files before installing any
service pack, and make sure you're comfortable with
troubleshooting your system in case it needs to be
troubleshotor just plain shot. The installation process is
easy enoughyou can order a free CD from Microsoft or download
the Service Pack via either the Web or Windows Update, then sit back
and let the installer do its work automatically. For an in-depth look
at Service Packs, turn to Appendix H.Service Pack 1 was primarily a bug-fixing pack. Service Pack 2,
however, provides many new features that cover everything from
configuring Windows' network tools to browsing the
Web more safely using Internet Explorer. These new features are
discussed throughout the book.
