About once a year,
Microsoft releases an
update to Windows XP.
These updates contain
all the fixes and
enhancements which have
been made available in
the previous year. The
updates (called Service
Packs) provide
convenient, all-in-one
access to the most
up-to-date drivers,
tools, security updates,
patches, and
customer-requested
product changes.
The latest Service Pack
for Windows XP—Service
Pack 2 (SP2)—is all
about security, and it’s
one of the most
important service packs
ever released. It
provides better
protection against
viruses, hackers, and
worms, and includes
Windows Firewall,
Pop-up Blocker for
Internet Explorer,
and the new Windows
Security Center.
