You can copy & paste your family tree into Word. Press Ctrl+A (to select all objects), Ctrl+C (to copy to the clipboard). Go to Word and press Ctrl+V to paste. You may also export your family tree to a metafile (Menu -> File -> Export Metafile). A metafile is like a JPEG however with a transparent background. The metafile may be inserted the same way you insert an image to your Word document.
To create a PDF, you need a "PDF Writer". I use the free PDF writer named "Cute PDF Writer". A PDF is created by "printing" your family tree into a PDF, so you need to use Menu -> File -> Print and select your PDF writer. Just before "printing", the PDF writer will ask you the filename to save your PDF.
