It’s no secret that Microsoft really, really wants all of its users to update to Windows 10. Not only are they giving it away for free (in classic Apple style) but they have also made it easy to upgrade by installing a Windows 10 icon on the system tray. It has also recently been confirmed by Microsoft that it is downloading Windows 10 installation files on to those computers whose users have opted into automatic updates. Therefore many users have already downloaded all of the files necessary, 3-6 GB worth of them, to start installing Redmond’s latest and greatest operating system whether they wanted to or not. Engadget has just reported that Microsoft has taken this a step further by now ticking the “Update to Windows 10” box in the Windows updater by default. Both the Windows icon and installation files can be removed easily enough but turning back the clock on an entire operating system update requires a little more time and finesse. Although Microsoft has told Ars Technica that making the OS install take place by default was an error on their part and that they will correct this, it might be a good idea to keep an eye on that next round of automatic updates so that you don’t get more than you bargained for.
