Windows Vista SP1

A little more than one year after its release, Windows Vista will receive its first service pack update in March. Microsoft says the pack will offer better compatibility with third-party hardware, increased reliability, tighter security, and better performance. But unlike the last Windows Service Pack release, Windows XP SP2, which offered users a new Windows Firewall, an improved Automatic Updates feature, and a pop-up ad blocker for Internet Explorer, Windows Vista SP1 is largely a code update, devoid of new eye candy, and very light on "must-have" features for home users.
