Windows 98 is a heavily web-integrated operating system that bears numerous similarities to its predecessor, with most of the improvements being cosmetic or designed to improve the user experience, but there are a handful of features that enhance system functionality and capabilities. These include improved USB support and accessibility, as well as support for hardware advancements such as DVD players. It was the first Windows operating system to adopt the Windows Driver Model. It also introduced features that would become standard in future generations of Windows, such as Disk Cleanup, Windows Update, multi-monitor support, and Internet Connection Sharing.
