On most computers, Windows Media Player will automatically open to view the video.   Consider saving the file for future use. See note below.  

On some computers, you may be asked to save the video file FIRST before viewing.  Consider saving it for future use, but  DO remember where you store it!   You will then be able to view the video even off-line.  

Note:  If the video plays automatically in Media Player, consider saving the file for future use.  While viewing the video, on the toolbar at the top of Media Player, click on FILE, and the scroll to SAVE-AS,  and remember where you store the file.     If you do not see the toolbar on the Media Player, right click at the top of the player, and click on “show classic menus” and the toolbar will appear.
