You might be in the process of acquiring Windows 10—whether you want the free upgrade or not. Microsoft has confirmed that it is “helping upgradable devices get ready for Windows 10 by downloading the files they need” in the event that owners decide to migrate to the new OS, even if they have heretofore passed up on “reserving” their free upgrade from Windows 7 or 8.
Windows 10 could be the best version of Windows. But, Microsoft risks alienating all of its customers when they have given an inch (automatic software updates) and the company takes a miles (willy-nilly use of GBs of storage behind the scenes).
Updates should be automatic, installation of whole new products should be by choice only.
