The latest version of Microsoft's free browser for opening and printing documents created with PowerPoint presentation software. PowerPoint Viewer 2010 allows you to view presentations created in PowerPoint 2010, as well as versions 2007, 2003, 2002 (XP), 2000 and 97. The browser seems to be an ideal complement when using competing packages (e.g.

OpenOffice), because they do not always reflect the original appearance of documents. With the help of browsers it is also possible to check whether a document created in a competitive program will be correctly read by users of Microsoft software.
