If you have a single computer to update, you can use Windows Update. Here is the procedure: 1. | Log on as a Computer Administrator and close any running applications. | 2. | Check to see if the Express Updates icon appears in the Notification Area on the taskbar. If it does, double-click it and ask to view the update details. If Service Pack 2 is listed, the files have already been downloaded and all you have to do is let Windows complete the installation by following the procedure in the previous section. | 3. | Open Internet Explorer and visit windowsupdate.microsoft.com. You may be asked to install the latest version of the Windows Update software. If a pop-up appears asking you to do this, click Yes. | 4. | Select a Custom install. From the list of available critical updates, select the Service Pack 2 Express Install. Windows will download the Service Pack installer and components. | From this point, follow steps 3 through 7 in the previous section, "Installing via Automatic Updates." |
