It's important to be able to update your WIndows XP home/Pro.,
otherwise you leave a lot of critical security issues un-patched.
Although your Windows can run without all the updates, but it is
very hackable and prone to online threats. If hard disk space is
limited, upgrade your HD to 80Gb or more.
And even after updating WIndows to SP2, you still need security
software like Norton Internet Security 2006 (antivirus and
firewall) for broadband connections. Otherwise, your PC will begin
to lag seriously after a while due to bandwidth robbery by
malicious scripts, trojans, and remote access of your PC.
Sometimes, your Home Page gets altered permanently....
