Windows 10 doesnt activate after upgrading with USB installation media
I have created Windows 10 USB installation media using the Media Creation Tool and used it to upgrade to Windows 10, however when the upgrade is done Windows 10 will not activate and says" Key has been blocked". I started the upgrade process from within Windows 7( I did not boot from USB). I also selected to skip updates because my internet is really slow i'm just trying to get through the upgrade to activate and clean install. I also selected to only Keep personal files because when I tried 5 times to keep personal files, apps and settings it kept getting an error and reverting to Windows 7.
The error code is get is 0xC004C003
How can I get Windows 10 to activate?
