One of the novel features that the guys from Redmond hope to debut with Office 2013 is Office on Demand. Office on Demand basically would allow you to use any of the Office applications as and when you need to use them without the usual installation.
With Office on Demand, subscribers will be able to download full-featured temporary versions of the Office applications that will run on the local PC. All they have to do is pick a computer with an internet connection and log-on into their accounts on the Office 2013 website. After the work and use of the application is over, it will automatically “disappear”.
It sounds like the way we use many of the available cloud applications including Office 365. But Office 365 is still a web app and is not as full-featured as its desktop counterparts. Office on Demand promises to be just as powerful as the desktop version. The Microsoft Blog states that it is the perfect solution for computers where you don’t have administrative rights to install software. Office on Demand will actually not install anything but will run as an temporary instance and you will not be able to set up shortcuts, register file extensions, or install system impactful extension points. You will have to be online to use it.
