According to the author, "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 Windows Update 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. However, I don't recommend uninstallation of the pack, if you don't have any problem. This is only for WINDOWS 98 SECOND EDITION ENGLISH. I highly recommend that you should backup your system before installing the pack. It contains only operating system updates. It does NOT contain Internet Explorer 6, DirectX 9, Media Player 9 and their updates" .....(free).....
