No It's Not!

Come hither, and understand once and for all: Microsoft Word does not come with any version of Windows whatsoever. Windows does come with Wordpad (formally Write) which is effectively a cut-down version of Word.

Many exchanges often occur because people think Word is part of Windows. This situation has been perpetrated by the common trend over the last ten years by the big manufacturers to bundle Word (or increasingly Works) with a computer. When the system has to be wiped eighteen months later because somebody put Limewire on it and screwed up the recovery partition, said exchanges occur. It usually later transpires that the Word in question was only the 60 day trial anyway and it'll be some more money to replace it with one that doesn't time out in two months time.
