Anyway, I got my LULZ.
Microsoft has generic keys to install Windows without activating it. The Windows install I have on my desktop is totally legit, the USB key image was obtained from Microsoft and the key is from them too, it’s not an activated copy but it’s good enough to run a couple benchmarks once in a while.
They have 90 day evaluation versions. You just have to reinstall every 90 days or it goes into super-asshole-limited mode. Even then, constantly reinstalling is a violation of the EULA. So…
As far as generic keys that you don’t have to activate… I’m pretty sure that’s your loosey-goosey European understanding of “copyright thingies” speaking.
