What is the meaning of this thread? Actually I can not understand anything about this thread this is really very much confusing. Please repost your question or query in proper understandable way. And secondly if you want any version of Microsoft windows like windows vista, windows xp, windows 7 and latest windows 8 then you can buy the original copy of any operating system. But about my opinion for hardware operation the Microsoft windows vista is the best and also the windows 7 is very good.
