Hello everyone, I downloaded Win 7 professional 64bit with Sp1 from MDl, from the sticky thread in this subforum, then made a bootable usb with this ISO using Rufus tool. I installed it on an old Intel Core 2 Duo computer for my parents to use, but even before i have done any updates to Windows, it told me the copy is not genuine and i have 3 days to activate it ( tho it might have downloaded something immediately in the background as im on a home network and internet is active as soon as windows boots up). My First question is : Why is it telling me i only have 3 days to activate, because when ever i used to install windows 7 ( any version ) it gave me 30 days before having to activate ? It also tells me in a popup message that in order to activate i must have a MAK or retali something or other. My other question is : which method, application, activation tool to use in order to activate this copy of windows ( Professional SP1 64 bit ) either permanently or for at least 6-12 months. Im a noob when it comes to this activating stuff, so im quite confused as to which tool to use and how. Im desperate for help and would be very greatful to anyone who could tell me exactly what what and how to do this. Thanks in advance.
