I have here a pc installed with windows 7 professional x86 RTM with user interface in pt-br. (1) How one made the change of language user interface to pt-br? Maybe using Vistalizator? (2) Is there already a iso or exe of Windows 7 Professional x86 brazilian portuguese version without sp1 ( build 7600 / RTM ). Is it possible to repair installation of this pc, which is unable update to SP1 (build 7601): (unknow) error 800F084F or 0x800f084f, (3) I mean using a "universal install disc" (ei.cfg removed)? (3b) Or using a windows 7 professional SP1 x86 ?
