** Do not upgrade to Windows 10. If you must, wait until it is available for purchase as a full, complete piece of software. Always upgrade via a "clean install" when upgrading Windows. This means removing the old version of Windows and installing the new version, usually from a DVD that you purchased. Do not click the icon in the Taskbar (the one we are removing here).
