I do own a computer with legit Windows 7 OEM copy, has all the stickers etc. Until end of the month it's still eligible for free Windows 10 update. The point is, for certain reasons I don't want Windows 10 yet. Mainly it's about hardware and software compatibility. I know from other machine owners that HW manufacturer didn't release completely compatible drivers yet. Beside that my Windows 7 is heavily customized in certain areas - like running specific critical processes and services that were modified by me personally and I am close to sure that they would not work properly in Windows 10. But as those issues could be solved in future, questions is: Is it possible to get Windows 10 HWID somehow but keep Windows 7 running? Is it possible to do so without wrecking my current Windows 7 installation? Would such HWID last for life or get disabled after some time by Microsoft - if I would hesitate with migrating to Windows 10? As for cloning drives, I've tried it in past and have really mixed feelings because parts of system weren't operational and everything ran very slowly.
