Updating to a Windows Vista Service Pack
Microsoft is continually updating and enhancing Windows Vista. Instead of releasing multiple updates individually, periodically Microsoft releases an update, known as a Service Pack (SP), which provides all-in-one access to the most up-to-date drivers, tools, enhancements, and other critical updates (which were formally referred to as hotfixes). Service packs as well as individual updates are available free for download and installation over the Internet using the Windows Update web site. With the enhanced Windows Update web site, Microsoft makes it easy to securely download and install this important update over the Internet. After you complete the installation, turn on Automatic Updates to help you keep your computer up-to-date and secure. If you’re experiencing problems with the service pack and need to reinstall it again, you can uninstall (or remove) it from your computer using Programs and Features in the Control Panel.
