Microsoft is downloading Windows 10 to your PC 'just in case'

Microsoft has confirmed that Windows 10 is being downloaded to computers whether or not users have opted in.An INQUIRER reader pointed out to us that, despite not having 'reserved' a copy of Windows 10, he had found that the ~BT folder, which has been the home of images of the new operating system since before rollout began, had appeared on his system. He had no plans to upgrade and had not put in a reservation request.I'm sure this is somehow my fault.
