The problem is that Windows Update uses ActiveX, and neither Opera nor Netscape (or Mozilla) supports ActiveX. That means they aren’t capable of using the site, or other sites that use ActiveX. Several plugins have been developed that purportedly allow Netscape, Mozilla, or Opera to use ActiveX controls, but at press time they were still works in progress, you’re better off staying away from then until they’re more solid.
For now, either use Internet Explorer for Windows Update, or use Window’s built-in automatic update capabilities. In Windows SP, right-click My Computer, choose Properties, and click the Automatic Updates tab. If you want Windows to automatically download and install updates, select, Automatic, and choose schedule. If you’d prefer that XP automatically download updates but tell you when they have been downloaded so that you can install manually, select “Download updates for me, but let me choose when to install them.” And if you only want to be notified when updates are available, so you can download and install them yourself, select “Notify me but don’t automatically download or install them.” When you’re done making your selection, click OK.
