, Microsoft finally announced that there would be six editions of Windows 7, just like there were for Windows XP and Windows Vista
. The company will release Windows 7 Starter (worldwide only via OEMs), Windows 7 Home Basic (only in emerging markets), Windows 7 Home Premium (retail and OEM), Windows 7 Professional (retail and OEM), Windows 7 Ultimate Edition (retail only during promotions and OEM), and Windows 7 Enterprise (volume licenses).
However, as part of its initiative to simplify the lineup, the software giant will only market Home Premium and Professional to average users. Most will be getting Windows 7 with their next purchase of a desktop, notebook, or netbook. (Speaking of netbooks, Microsoft also noted last week
that all editions of Windows 7 will work on netbooks and it will be up to the OEM's discretion as to what editions they want to offer on each product.)
If you won't be going through an OEM, you'll either want to purchase a full retail copy of Windows 7, a cheaper upgrade edition, or the OEM version (usually the cheapest and best way). While Microsoft has not given details on pricing for any of the three, the company has agreed to offer upgrade options to both Windows XP and Windows Vista users, and they are worth outlining in detail.
