Microsoft announced a free upgrade for Windows 10 will be made available to customers running Windows 7, Windows 8.1, and Windows Phone. The free upgrade will also apply to Enterprise versions of Windows 7 and Windows 8/8.1 Enterprise. The end is near for Windows Server 2003, which reaches end of support on July 14, about five months away. Microsoft has targeted June for the Windows 10 RTM release, as opposed to August, and manufacturers will have Windows 10 on devices in time for back to school shoppers.”]
