Torrents are a big no for me (Damn ISP throttling P2P B/W) Im planning to get the Core ISO from here /59229-Windows-8-1-x86-x64-ISO-Download-ALL-VERSION-LANG-HTTP-links And use this thread to make a Pro ISO (slight revisions to the commands) /35650-Creating-a-Windows-8-1-AIO-with-Media-Center-manually Is it possible? or could someone give me a Win8.1 Pro x64 ISO with http download?
Is there a way to upgrade already installed 8.1 Core (KMS activated) to 8.1 Pro without reinstalling entire Windows again?
Should be possible through the 'Add Features to Windows' wizard. Valid 8.1 Pro key (no KMS) or the generic 8.1 Pro install key.
