SkyDrive is back, and full integration in Windows and Mac
SkyDrive for Windows is the easiest way to access your SkyDrive from your PC. When you install SkyDrive, a SkyDrive folder is created on your PC. Everything you put in this folder is automatically kept in sync between your computers (PC or Mac) and SkyDrive.com, so you can get to your latest files from virtually anywhere. Whenever you add, change, or delete files in one location, all the other locations will be updated.
If you forgot to put something in your SkyDrive folder, you can still get back to your PC to access all its files and folders from SkyDrive.com
