7. Downgrade Rights. If you acquired a device from a manufacturer or installer with a Professional version of Windows preinstalled on it, you may use either a Windows 8.1 Pro or Windows 7 Professional version, but only for so long as Microsoft provides support for that earlier version as set forth in (aka.ms/windowslifecycle). This agreement applies to your use of the earlier versions. If the earlier version includes different components, any terms for those components in the agreement that comes with the earlier version apply to your use of such components. Neither the manufacturer or installer, nor Microsoft, is obligated to supply earlier versions to you. You must obtain the earlier version separately, for which you may be charged a fee. At any time, you may replace an earlier version with the version you originally acquired.
