I have been with the Insider program from the beginning, upgrading with each new build. Upgraded to 240 on the 26th July. Today it has deactivated, I restored to an image I created on the 4th August. Initially it was activated, then a couple of minutes later it tells me it is 'not activated'. My other computers 3 Laptops, 1 Tablet and additional Desktop were upgraded from Windows 8.1 they remain activated. It is only the Insider copy that has deactivated. Anyone else experiencing this?
