There are times when you may have a powerpoint presentation which you have recieved via mail or some other way. Now you want to view the power point presentation but you don’t have the Microsoft Office Powerpoint installed on your computer.
Microsoft has just released PowerPoint viewer which allows you to view powerpoint files. It lets you view full-featured presentations created in PowerPoint 97 and later versions with full fidelity. This viewer also supports opening password-protected Microsoft PowerPoint presentations.
Note: However, you can view and print presentations, but you cannot edit them in the PowerPoint Viewer. It works with powerpoint presentation files created in PowerPoint 2010, 2007, 2003, 2002, 2000 and 97.
This powerpoint viewer although is quite heavy in size [ around 60 MB ] and resource consuming as per CPU usage, another best alternatives to view a powerpoint file could be the online free web services like google docs or docs.com by Microsoft.
