When it launches this fall, upgrading to Windows 8 Pro will cost just $39.99. This aggressive pricing isn’t limited to recent Windows owners — it will be available for PC owners who are currently running Windows XP, Windows Vista, or Windows 7.
Downloadable from Windows.com after launch, you’ll also be able to add Windows Media Center for free from the “add features” option within Windows 8 Pro after you download the update. Thanks Microsoft for showing some heart! :)
