The cloud version of Microsoft's top selling product was handed for free to over 1,000 elementary and secondary Hong Kong educational institutions today.

The Office 365, an online version of the Microsoft Office Suite, is a service which provides access to programs such as Microsoft Word, Excel, and PowerPoint anywhere. The service also includes business oriented e-mail services and conferencing.

The giant tech firm launched their investment into the Hong Kong education sector today, according to reports from the city. The program will last for three years, which was implemented in partnership with the city's Education Bureau.

According to news reports, Microsoft's efforts will benefit over 800,000 students and 50,000 teachers. The cloud technology will allow the expansion of education strategies.

We believe that the cloud-based learning model and practice will help teachers to prepare more interactive and collaborative learning programs for their students," said Hong Kong's Secretary for Education Eddie Ng Hak-kim.

Analysts consider the Office Suite as Microsoft's most reliable cash cow. Consumer-generated revenue from the Office line was US$1.5 billion, enough to keep the company afloat despite losses from PC sales.
