Microsoft provides many online and desktop programs that let you do so much — you can edit and create Office files, run an entire Operating System known as Windows, and also store and share files. In today’s connected world, all these programs need to link to external “services” for sharing and using your personal documents. So what are these services? Well, most of these may be something you use everyday such as Facebook, LinkedIn, Flickr, etc. Microsoft also has its own services such as OneDrive from where you can use files which are saved online, and Skype through which you can make calls.
