Microsoft has created a handy chart that lists all the possible Windows 7 upgrade paths. Users of Windows XP or Windows Vista Starter will always have to do a clean install, only Windows Vista users who are upgrading to the corresponding Windows 7 edition of their present installation will be able to do an upgrade. European and Korean users will be required to do a clean install as well, as upgrade versions won't be available on those regions. Due to legal problems, Microsoft decided to remove certain applications like Internet Explorer and Windows Media Player from those editions.
