Windows 7 Professional is available by all OEM partners and has the same features as Windows Home including the graphics of Windows Home Premium. In addition, it includes features and applications useful for small business and people working from home. These are features like more advanced network usage and database protection.
These are small features for a whole new version and Microsoft is probably going to have a hard time convincing business that they should use this version rather than the Windows Home. But Microsoft has previously proved that they got the marketing skills to really ‘move’ people.
