Microsoft Won't Support Non-Genuine Windows 10 Upgrades
VentureBeat heard from the company that, “Although non-genuine PCs may be able to upgrade to Windows 10, the upgrade will not change the genuine state of the license.
Non-genuine Windows is not published by Microsoft. It is not properly licensed or supported by Microsoft or a trusted partner.”
It’s likely these non-genuine PCs won’t receive security updates, and their Windows installs may expire after a certain period of time.
Microsoft said it will “provide a mechanism for non-genuine Windows 10 PC devices to ‘get genuine’ via the new Windows Store, whether they are upgraded versions of Windows or purchased. We will have details on this as we get closer to launch.”
