*cough*AHEM*cough*, erm might I just interject here and state that the correct term should be Microsoft Windows, or Windows 2, 3.11, 95, 98, Millenium Edition, NT, 2000 or XP. The term windows PC merely implies a PC capable of running one of the many windowing applications out there, which include Gnome, KDE, Enlightenment, X11 and others. It could also technically be used to describe Mac OS, GEM, Lisa, and all those other lovely windowing programmes that have existed before Microsofts' bastard version.
