You also might try the freeware utility ROM (Revenge of Mozilla). It rips out IE and the html desktop, replacing it with the much sleeker Win95 desktop. It also surgically removes active-X, windows update, and a few other unethical additions, IIRC. This makes Win98 a much better host for KM. <g>
A few caveats: ROM tears a lot of IE-related stuff out, so make sure you know what you're doing. It supports Win98 only, it has to be applied over a fresh os installation, and its author no longer supports it. Hmm, quite a testimonial ...
Here are a few download sites. They all seem OK right now ...
