As the title says, I've done a EFI installation of Windows 7 Home Premium 64-bit. Could someone tell me any possible loader/program or other that can activate Windows? Unfortunately Daz's loader doesn't work, he kindly suggested me to try: timesurfer's IR5 - I would like to leave this as a last option since it runs a process in the background (if I've understood correctly). BIOS mod - Don't know what it is, but my motherboard has UEFI, so how does it work? HAL7600 - It seems OK. I would like it to be as "stealthy" as possible, but I'm fine with anything since I've less than a month to activate. Thanks for any help.
