A Microsoft file hosting and synchronization service.
I believe that it is wrong for it to default to this setting. It should ask if you want the files saved locally only, saved locally and synced, or saved on the cloud and made available. I only want my pictures and computer settings backed up, not every little thing that I am working on and saving. I tend to save items that I am working on to my desktop so I see them and finish them, and then delete them. Now I have to go digging for them or set something special up for what should be common sense. I chose Desktop, that means Desktop, not three clicks away in a cloud folder. I am having to explain where people's files are continually. I feel that this is not being done for convenience. I feel that they are doing this just make you pay for storage that you don't really need.
