Microsoft Pushing Out IE8 Through Auto Update
Microsoft has begun pushing out Internet Explorer 8, the latest version of its Web browser, to Windows users who are signed up for automatic software updates.
If your system has Automatic Updates turned on, you may have already been prompted to install the software. Whether you use IE on a regular basis or not, it's probably a good idea to accept this update, for a couple of reasons.
One is speed, both in startup and in normal browsing. From my own, unscientific testing, IE8 simply runs quite a bit faster and smoother than IE7. Various Web sites and blogs have sought to pit IE8's speed against those of other browsers; I won't attempt that here. My take: If you must have any version of IE installed, this is the one you want.
