Hi, Please excuse this question if it is rather dumb but could someone please be good enough to explain to me which types of Windows 7 are used in the business world? By type, I mean VLK, Enterprise or Retail etc and not the sub variant of Home, Pro or Ultimate. Firstly, would a company with 5000 employees worldwide use a Retail version of Win7 or a VLK version or an Enterprise version. Secondly, what type of Win7 would be used by global PC builders and vendors such as HP, Dell, in their machines preloaded with Win7. Thx
