There may be some way, if you are computer savvy enough, to get WIS onto your home computer, it takes some "professional" version of windows to run it, I think XP, I'm not "up" on all this computer stuff so I'm not sure.
I've heard stories of finding the WIS discs on EBay. Probably not really a real honest thing to do, like selling pirated CD ROMs of other varieties, but there is another option for you. But again be aware of the system requirements to run them.
