are u using a genuine copy of windows??
my dell runs on a genuine copy but not the other notebook..coz the genuine one works only for dell ..but i dont feel any difference between both

Are you saying that one copy is not licensed, therefore illegal?
If it is illegal, we can't have it publicized like that on FLL.
Yes my friend , We could publicize it and contact the authorities , get your ip traced till your house and throw you behind the bars. Its a big offence to use a pirated windows .
Thats the best way to use good Internet and Genuine version is very secure for our data transfer and virus protection also. I am using genuine version at office and at home it is not the genuine. So I can see the difference easily.
