Okay, before I try to ask questions I did look around but there wasn't really any place that answered these questions concisely. So here they are: What is the difference between MICROSOFT.WINDOWS.8.ENTERPRISE.RTM.X86.VOLUME.ENGLISH.DVD-WZT and en_windows_8_x86_dvd_915417.iso (MSDN)? What is the difference between Microsoft Windows 8 Enterprise RTM compared to Windows 8 on MSDN? What does the Windows 8 Professional RTM Final have compared to WZT's Windows 8 Enterprise edition? What is the "safest" edition of Windows 8 I should download? I am getting the non-N so I get Windows Media Player, but should I go with 9200.16384.120725-1247_x64frev_Enterprise_VL_HRM_CENA_X64FREV_EN-US_DVD.iso or en_windows_8_x86_dvd_915417.iso ?? Thank you if someone could help clear some questions.
