I just received a new computer. I have a zip file that I have created from my old computer. Ofcourse, I am not able to use it, because Microsoft has taken away the ability to override their security system and there is no unblock option. So, now I have a software which is not userful for me at all. I have seen a click on unblock but I have no unblock option, so if anyone knows how this can be solved, then please tell me. Thanks.
