Ah, no, it wouldn't find keys for you, its not illiegal like that
Itsuseful though for finding all about your PC and what it contains though.
As with a ethernet adapter though (you might have to get two, but there very cheap, about a tenner each)
you'd buy one for the Win98 old PC (don't worry about updating, all you'd need to do is fit it, and install the drivers and you'd be done),
and then install another one on the XP machine (since the XP computer is already using one for internet, unless theres a way of splitting one),
Finally you'd connect an ethernet cable from one to the other, and set up a simple home network to share the printer and other resources.
I'm sure thats possible. Anyone here know i'm right so I can assure myself i've given the right info? Especially since its XP to 98
I hope this helps
