View PowerPoint files Online
The easiest way to view PowerPoint files online is with Office Web Apps and Skydrive. In order to use this service you don’t need to pay for a license but you need to have a Windows Live account or Hotmail account. Once you open your inbox and sign in Hotmail you are able to upload your PPT files and pptx files to the web apps and open it as a presentation as we explained earlier in open PowerPoint presentation.
You can create and edit PowerPoint presentations using this approach and it is a convenient way to view PowerPoint files online if you don’t have Microsoft Office installed in your computer or if you need to share PowerPoint files online. Also, this is a good way and alternative to view PowerPoint presentation without PowerPoint.
