Thanks to Tim @ Majorgeeks.com for the Heads up! Microsoft has never released a service pack for Windows98 SE. But I made a Service Pack for Windows98 SE users. It contains all Windows98 SE updates from WindowsUpdate site and more.
It is a self-extracting and self-installing pack like Microsoft's update files. Thus, you cannot choice files individually. However, the pack installs only required fixes for your system. Uninstallation is possible from Add-Remove Programs.
