The serial is embedded in the controller on the hard drive, you can't change this.
Well it can be cloaked, there's software out there to do it. But I only see two reasons for someone wanting to do this.. 1) Circumvent some software's licensing and 2) Spoof what kind of hardware you have in the system
You should take this up with the creators of the game instead of circumventing their banning system (which is most likely a violation of their Terms of Service/Software License)
Are you saying theres a embedded login dell wind 7 32 bit ( sorry bout thatyou are wrong...
pbdownforce can change this serial number but only works on 32 bit windows
I have been banned for no reason... in game
