Windows 7 Upgrade Options

With the release of Windows 7 RTM to MSDN subscribers Microsoft have unveiled the upgrade options from previous version of Windows.

Basically "Custom Install" means that you will need to format your machine with a fresh installation of Windows 7 (which is what I would recommend anyway, even if you have the option to upgrade).

In true Microsoft style the upgrade paths are far more complicated than they ever needed to be, especially when you compare them to Mac OS X.
