Stealth1024,
50% legal is like being 50% pregnant.
Microsoft does distinguish between OS and application licenses. They allow NON-simultaneous use of the same copy of Office on, say, a desktop and a laptop. But not the OS. So far they've been able to make it stick in court. Obviously, the chance of an individual getting caught for "abusing" the OS license is slim -- unless s/he talks about it online, of course. Microsoft, and other software companies, have subpoenaed user records from online forums and chat rooms to locate people who've discussed so-called piracy-related behaviors online.
I try gently to dissuade anyone from even using shareware without paying for it -- on philosophical grounds. Heck, I even send postcards for postcardware!
But Microsoft is a very different matter. I've been very worried about Billy G. lately since recent stock market fluctuations are reported to have reduced his net assets to less than a mere $100 billion. You must pay Billy the proper license fees for his OS. How else will he build a new indoor landing strip on his cottage?
