Sony supports Microsoft® Windows® Operating System Service Packs.
Microsoft offers Service Packs to provide updates and fixes for the Windows XP and Windows 2000 operating systems. Service Pack updates are only for Sony VAIO® Computers that either shipped with or have been upgraded to the Windows XP or Windows 2000 operating systems.
Note: Depending on when your Sony computer was manufactured, it may already come with one or more Service Packs preinstalled. You can check this information in the computer control panel system properties.
IMPORTANT: The installation of a Windows Service Pack may cause unexpected results on certain VAIO® computers. Before installing a Windows Service Pack, please check your computer model-specific support page for information about required updates or known issues.
