Microsoft confirmed that it has been pre-loading the Windows 10 installation bits onto devices whose owners have not “reserved” a copy or expressed interest in the new OS. The move has upset some users of Windows 7 and Windows 8.1, who have complained that the unsolicited downloads have caused them to exceed their Internet providers’ data caps or seized storage space without their consent. If Windows 7 or Windows 8.1 device owners have Windows Update set to the default and Microsoft-recommended option that lets the operating system download and install security and other bug fixes automatically in the background, Microsoft will push the Windows 10 upgrade files to the drive. The upgrade, which can range in size from more than 3GB to nearly 6GB, is placed in the hidden "$Windows.~BT" folder, a long-used destination for Windows upgrades. It will sit there, presumably until the user expresses interest to install Windows 10.
