Even when running the Windows setup from within Windows, this is the option you get when upgrading from Windows8 developer preview to Consumer Preview. What a User Friendly screen! If I can “chose” what I want to upgrade, why only give me one option – which is nothing? Interestingly I could keep settings if I was upgrading from Windows7 – so it’s weird how you can’t keep settings from the Developer preview to the consumer preview. The Windows 8 faq has a table of what can be kept when upgrading from previous versions of Windows.

It might be a good idea to have the upgrade options within the application itself and not as a link to an external website – this way the user gets to see what options they have.
