I don't think I want to continue being a crash dummy. I don't mind messing around with a new OS but I am not going to hang around and test apps.
This is a little odd, also:
"If your system upgraded from a Genuine Windows 7 or Windows 8.1 license it will remain activated, but if not, you will be required to roll back to your previous OS version or acquire a new Windows 10 license. If you do not roll back or acquire a new license the build will eventually expire."
I would have thought that it could detect, before upgrade, that it was not a genuine copy. "Eventually expire"? I see a hole in the system there, ready for the pirates to exploit.
That looks identical to the system already in operation. It remains a "Catch me if you can" situation.
