Hi All, I am new to these forums and have had a quick look around and like what I see. Sorry if this question has been asked millions of times but I am really confused I have been carrying out work on computers for friends and family off and on for the past year. Work generally ranges from virus removal to upgrades to OS installs. I would say around 50% of the time the computer is given to me with the OS disk which the computer came with (Vista/Win7) and the label on the side/bottom of the machine with the product key is still there. For the other 50% of the time I struggle to find either the OS CD or the product key. I have seen the OS .iso files which can be downloaded from these forums. What I would like to know is, are these .iso files legitimate? If not then is there anywhere I can download/purchase the OS CD/DVD’s and is there anywhere I can purchase product keys? My plans moving forward is to carry out more work on a larger scale and I don’t want to be using any illegal software/product keys. Thanks in advance!! Nav
