Store your Office documents in SkyDrive, and Office Web Apps lets you view and edit them in your web browser. That’s perfect for making quick updates (no need to start up an Office program), on just about any computer that’s connected to the Web. You can avoid the hassle of sending documents as email attachments, and skip the extra step of saving them as PDFs. Instead, store documents on SkyDrive, where you can link to them in email, on social networks, and in your blog. Word documents, Excel spreadsheets, PowerPoint presentations, and OneNote notebooks display in the browser just as they look in the Office programs.
To get started, go to http://skydrive.live.com, sign in, and click Add files. Pick documents that you want to be able to share easily, or be able to access on any computer. When you can see the document on SkyDrive, click it. It opens in Office Web Apps.
To sign in to SkyDrive, you need a Windows Live ID. If you don’t already have one, click the Sign up button at the SkyDrive sign-in page and fill out the form. Your ID will be based on your email address. If you want to use an email address you already have (if you don’t want to sign up for Hotmail), click the Or use your own email address link.
