I imagine a lot of machines running XP won't be able to run 8.1 Your imagination is completely wrong. Here are the minimum specifications: http://windows.microsoft.com/en-us/windows-8/system-requirements http://windows.microsoft.com/en-us/windows-8/system-requirem... IIRC even the minimum screen resolution of 1366x768 Your memory is also completely wrong. Windows 8.1 does not have a minimum resolution of 1366x768. In fact, if you review the system requirements link above, you'll see that it works at less than 1024x768 but that certain features require 1024x768. Can you help me understand the purpose of your comment? I mean, obviously - you had no idea what you were talking about. You even knew it because you used weasel words like, "I imagine" or "IIRC". It makes me think you had some agenda to spread FUD about Windows 8.1 not working on older hardware.
