Windows 10 will not activate after upgrade / clean install?
Hey Guys
I upgraded from 8.1 (genuine Sony Vaio ) using the media creation upgrade option, it installed and activated to windows 10 pro.
I then used the same media creation tool to download the iso and used Rufus to put it onto a usb so that I could do a clean install.
I installed it and skipped the parts prompting for a product key, however once it loads up when I try to activate it states 0xC004C003 details section says the key has been blocked?
Have I missed something?
Any help appreciated.....thanks.
