To aid users of older Windows versions with non-broadband access to the Internet, Microsoft is considering releasing a CD-based security update product that would bulk install the security updates the company now offers on Windows Update. A beta test of the potential product, dubbed the Windows Security Update CD beta, will start soon, according to an email the software giant sent to testers last week, and will be aimed at Windows 98, Windows 98 Second Edition (SE), and Windows Millennium Edition (Me).
