Now that Microsoft has rolled out Office 365 Home Premium the free beta trial period is over. (You still get the first month free.)
Unlike previous retail versions of Office, Office 365 is a subscription service. You pay a monthly or annual fee to use Office and you can install Office 365 on up to any combination of five Windows PCs or Macs.
One of the new features of Office 365 is that you can "stream" the applications you subscribe to using a feature called "Office on Demand." Office on Demand works with Word, Excel, PowerPoint, OneNote, and Publisher and works with any PC that allows you to login to your Microsoft account that has a persistent Internet connection.
The video below gives you all the details to get started.
