<<So basically, it only the Enterprise Edition that'll do an upgrade?>>
Not at all, the way that I interpret what is there.
<<Now, the fact that Vista is 'OEM' and W7 is 'Retail' shouldn't make a blind bit of difference.>>
Well...it makes a difference to Microsoft
, even if not to you.An OEM license tied to a system put together by an OEM
(HP, Lenovo, eMachines, et alia)...cannot be used to "upgrade" a system with a retail version upgrade install
: ,"On PCs purchased with Windows XP or Vista preinstalled by the computer maker -- which slap an "OEM" license of Windows on the machine -- users can install a Windows 7 upgrade edition on that system's blank hard drive, but on no other, Ligman added."
OEM systems have theeir own upgrade options, for those who do not want to do a clean install.
