I understood your question just fine. The people I've seen on Hexus who said that s/he entered a key also stated it didn't work - those being Jonj1611 & Lil-Diabo. Those that did an in-place upgrade had an activated Win10 at the end of the process. I'm not sure what happened with Stevie Lee's system, as he is the first person I've seen doing an update from an extracted ISO to HD.
For those that tried using the clean install from the start, and got "Error code: 0xC004C003. Activation server determined that the key has been blocked", pull up an administrator command line (
OMG DOS) and type the following command:
slmgr.vbs /ato
You may have to do this a few times, as the activation servers got slammed hard today (over 14 million upgrades went through on day 1. That's roughly 162 per second for those doing the math -
Source).
As an FYI to everyone, neither Speccy nor Magic Jellybean are returning the actual license key that's generated. They're posting a generic code that everyone seems to be getting (VK7JG-NPHTM-C97JM-9MPGT-3V66T). This is NOT your Win10 key. I'll post a VBS script that returns the actual key in its own thread so more people can find it. Can you use this key to activate another machine? I don't know, and I'm not apt to test it. I'm not going to say your usage is unique, but it does seem a bit unusual...
