What is the difference between windows 7ultimate and extreme ? any one please

"extreme" is an unofficial release of Windows 7 created by a release group project-os

ultimate is the actual official version of 7 release by Microsoft

its generally a common feeling the unofficial/custom versions of Windows should not be trusted, so Id stick with ultimate

Agreed, unless its an untouched image of the orig CD, and the CD checks match I would not touch it with a 50 ft pole!

basically both are same or different program ?

no..
not really

they are both Windows 7

but...

Ultimate is the official legitimate release by Microsoft

"Extreme" is made by another group other than Microsoft so it is not legitimate, probably contains malware, and is not really supported by Microsoft

just go with Ultimate, Extreme just comes with a few other things (themes and programs) you can just install yourself to ultimate. so yes they do the same thing, but they are different.

i agree to it from what i've been told from xtreme i believe what they say u cant tell what they really put into the iso even if u scan it with a virus protection they can put scripts and key loggers into the files and get all ur info.

There are only 2 things you should make sure you do when settting up a PC.

USE A CLEAN OS WITH A CLEAN KEY
USE THE BEST POSSIBLE ANTIVURS WITH A CLEAN KEY

There rest of the stuff you use once thats running, you can pirate your shit to your hearts content.

But if your running custom windows builds and cracked anti-virus I can guarantee your probably infected and don't even know it.

i will keep in my mind when i install OS and thanks for the information
