Service Pack 1

Microsoft® is continually working to improve its software, and as part of this effort, it develops and releases updates and fixes for recognized issues. On a regular basis, Microsoft combines many of these fixes into a single package and makes the package available for you to install on your computer. These packages are called service packs.

Microsoft® Windows® XP Service Pack 1 (SP1) contains the latest collection of updates to the Microsoft® Windows® XP family of operating systems. These updates pertain to:

• Security issues (including the Windows XP Update Package)
• Operating system reliability
• Application compatibility
• Windows XP Setup

Note

If you have not yet installed the Windows XP Update Package, you only need to install Service Pack 1 because the security update is included.
