Now that Windows XP has been essentially cast adrift by Microsoft, at least as far as we consumers are concerned, we start to hear the wistful musings about a popular operating system being put out to pasture. However, the reality is that Windows XP was pretty controversial and unliked by many for a good part of it's life.

Gone were the days of buying one copy of the software and installing it on multiple machines. With Windows XP, every system would need its own copy.
