2-49Lesson 6 Activating and Updating Windows XP Professional

When you install new operating system components after a service pack has been

installed, Setup requires both the operating system and service pack installation files.

This allows Setup to install the updated version of the component.

To Uninstal a Service Pack

By default, the service pack setup program automatically creates a backup of the files and

settings that are changed during the service pack installation and places them in an unin-

stall folder named \$NTServicepackUninstall$\ in %systemroot%. You can uninstall the

service pack through Add/Remove Programs on Control Panel or from a command line by

running Spuninst.exe from the %systemroot%\$NTServicepackUninstall\Spuninst\ folder.

Note If you installed a service pack without creating a backup, you cannot uninstall the ser-

vice pack.

Practice: Configuring Automatic Updates

In this practice, you will configure Automatic Updates to download and install critical

updates automatically.
