• If you have Windows 7 Home Premium, Windows 7 Professional, Windows 7 Ultimate, Windows 8 Pro with Media Center, or Windows 8.1 Pro with Media Center and you install Windows 10, Windows Media Center will be removed. For a limited time (the “eligible period”), on systems upgraded to Windows 10 from one of these older versions of Windows (a “qualified system”), a DVD playback app (“windows DVD player”) will be installed. Note: the Windows DVD Player may not be installed immediately; it will be installed after the first successful Windows Update. The Windows DVD Player will be available for purchase from the Window Store for systems that (i) are qualified systems but the eligible period lapsed; (ii) are non-qualified systems; or (iii) were qualified systems but windows 10 was subsequently clean installed (in this case, Windows Update cannot detect that it was previously a qualified system).
