Microsoft PowerPoint 2016 is the current version of Microsoft PowerPoint for Windows and Macintosh. It is the standard version of PowerPoint to be found on lab PCs, faculty PCs, and multimedia classroom PCs.
Note: For Office 2007 or later, the default file format is .pptx. This means that any computers running Office 2007 or 2008 will be able to access such files, but if someone tries to access such a file from Office 2003 or 2004, it will not work. To ensure backwards compatibility, simply select the .ppt format when saving the document to ensure that Office 2003 or 2004 users can open the document.
