This is NOT a screenshot of copyrighted computer software. It is a screenshot of an OUTPUT from software. Microsoft has NO copyright control over my book, even if I composed it in MSWord. The screenshot has no file structure, no menu data, no logos. Everything in it is user selectable with the possible exception of the gridlines, which even Microsoft wouldn't try to claim a copyright for.
The copyright for its contents cannot be held by the author(s) or the company that created the software, and the contents of this post cannot be subject to copyright as a product of MS Explorer.
This is the kind of mindless tagging that is slowly strangling Wikipedia... — Preceding unsigned comment added by 214.4.238.180 (talk) 18:38, 6 January 2012 (UTC)
