So heres what happened, my laptop hard drive completely failed on me so i had to buy a new one. I download a the exact win7 hp 64bit iso onto a usb so i can redownload. I get to the part where i put in my product key so i use the oem one on my laptop but it doesnt work. Will microsoft supply me with a new one since my hdd died on me and im using the same laptop? Thanks in advance
