The main features in Office 2013 are associated with saving and sharing files online. With that goal in mind, you will need to get a free Microsoft account (previously Windows Live ID) if you don’t already have one. You can then log in to your Microsoft account to access your SkyDrive, which is an online cloud (storage space) for your documents and files.

There are a lot of benefits of Using a Microsoft Account. Some of them are:

• Access and edit documents in your web browser: Suppose you don’t have a computer, or your computer doesn’t have Microsoft Office. In this case, you can still use the free Office Web Apps to edit documents in your current browser. Office Web Apps include simplified versions of Word, Excel, PowerPoint, and OneNote
• Share files: You can easily share your SkyDrive (cloud) files with friends or family. You can define whether they can edit or only read the files. This option is great because multiple people can edit one document at the same time (also known as co-authoring)

If you don’t have a Microsoft account, you can easily open one within the Office application (i.e. Word, Excel, …)
