Microsoft Office is pre-installed for free on Windows RT

Office suite on Windows platform tablet running ARM chip will include Word, PowerPoint, Excel and OneNote.

Office on Windows RT will be free.

One of the most distinctive features of Windows RT operating system compared to other platforms such as iOS or Android is the Microsoft Office office application pre-installed. This means that users will not have to pay extra for Office suite nor need to worry about compatibility when running on their device.

However, this is only part of the story because in the detailed information published, Microsoft said that Office for Windows RT will have some features cut off. This suite of applications will include Word, PowerPoint, Excel and OneNote but Outlook, Access or Publisher will not appear.

New Office will be changed interface to better fit the touch screen.

In addition, users do not enjoy all the same features on Windows RT as x86 devices running Office 2013. In particular, there will be no support for macros, add-ins or ActiveX.

When Windows RT is introduced on October 26, Microsoft will integrate a preview version of Office Home & Student 2013. Free updates to the full version will be available at the time the device reaches the user's hands.

Microsoft Office has been redesigned to be more convenient with touch screens. However, users still completely use the software with the mouse, touchpad or keyboard like a regular computer as before.
