What to Expect from Windows XP SP2
Due to the number and type of security features it delivers, Microsoft® Windows® XP SP2 is a significant update. Here are a few tips about the time and computer memory required to install SP2, what you will see as you install it, and what might change after you install the service pack.
Hard Disk Space
You need at least 2 gigabytes (GB) of available space on your hard disk drive. To check your free hard disk space, from the Start menu, click My Computer, and right-click Local Disk (C:) or the name of the drive you are installing SP2 on, and then click Properties.
Also, make sure that your computer meets the minimum system requirements for Windows XP SP2.
The time it takes to download and install SP2 depends on many factors, but especially on the following:
Backing up and restoring
Before you update your computer, you should always back up your files and personal information. During installation, SP2 will also set a restore point for you. A "restore point" lets you "roll back" Windows to a previous state if you encounter difficulties using or installing SP2.
Restarting your computer
You will need to restart your computer to complete the SP2 installation. Before you restart your computer, save your information and close all open programs, and make sure no one else is logged on (if you use Fast User Switching).
After you restart your computer - and only if you have not done so already during SP2 setup - you will be prompted to turn on Automatic Updates. Using Automatic Updates is the easiest way to keep your computer up to date. With Automatic Updates, you do not have to remember to visit Windows Update frequently. You can schedule a time to download and install updates, but if you want to turn off your computer before the scheduled time, you will be able to install updates just as you turn it off.
Windows Security Center
Available from the Control Panel, this new feature provides a single place to manage your three security essentials: Windows Firewall, Automatic Updates, and your antivirus software. Security Center recommends security settings that you can use to help protect your computer. It also provides links to important information about other SP2 security features.
Using your existing programs
SP2 can change how some of your existing programs work, especially programs that use the Internet. These changes are designed to help protect your computer and your information. For example, Windows Firewall is turned on by default. For more information about using your programs with SP2, go to the Security Center in Control Panel and then click What's new in Windows to help protect my computer.
