After much research, test, configure, I managed to assemble a "lite" windows 7 ultimate x86 - en. Was removed much "useless" for a user. The idea was to make fully functional for a more corporate user, ie, after the network, sharing, printers, drivers ... Was removed, for example, the Tablet PC, Windows Media Center, SUPPORT THE SPEECH, and other stuff that only weighs the windows and let him "fat."

Requirements:
> 1.0 GHz processor supports 32-bit platforms (x86) or 64-bit (x64)
> 512 MB ??of RAM (32-bit), 1 GB of RAM (64-bit) (depending on version)
> 16 GB of available disk space (32-bit) 20 GB of available disk space (64-bit) (depending on version)
> DVD
> Video card with support for DirectX 9 graphics and 64MB of memory (for Aero)
