If you're stuck with a Windows 98 computer—and you haven't made the switch to Linux on it to get a brand new system—you may want to take advantage of this freeware update for Windows 98. The author of this freeware 98 SE Service Pack shares this point:
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 individual files.
His only warning is that the service pack be used on Windows 98 Second Edition English version. You are encouraged to make a backup of your computer system—perhaps using tools previously suggested in earlier issues—and are required to have at least 32 MB of RAM.
