Have you changed your Computer name from how it was before? I had the same problem after clean installing and picking express setup that gave the gibberish PC name. After changing it to how it was before system activated immediately.
Yes I did change the name, but that was like back when I installed 10240 over a week ago. Was activated until restart this morning.
Try changing it back to how it was before. If you want the new name, then update again from scratch, make sure you are online when the previous system (7/8) shows as genuine and active, before restarting. It looks silly but it did work in my case.
I'm an insider too and also changed computer name several times and still activated, thats got to be something else.
I upgraded from a older build not from 8.1 Don't remember what the old name is that Windows gave my computer.
No problem they released this tool on 7/7/2015 with absolutely no announcement whatsoever, like they really did not want us to know about it and use it. Also if you get an update that plays bad...just uninstall it and then use the hide update troubleshooter tool to hide it forever.

Use new drivers if you have nvidia. i don't have ati so i don't know about that.
10.0.10240.16384 is official RTM. Tom Warren confirmed that. Mary Jo Foley confirmed that. Paul Thurrot confirmed that. WZOR finally confirmed that. Chinese OEMs are leaking official ISOs, and confirmed that too. Even MS support, who I contacted personally yesterday, told me that is RTM and that will become "Final" by simply installing daily OS "rollup" + Store updates till 29th of July on top of it (without needing to reinstall or upgrade again to a new build). Just Deal with It.
Is true that Windows 10 RTM build 10400 (Gold build) will be free on 24th? I don't think that build 10240 is the official RTM
