    Hi. I have changed my motherboard and had to refresh a windows 10. I have noticed that need to activate windows but didn't have time for that as it was possible to do that by phone only. Week later I wanted to activate but activation by phone was gone and have Error code: 0xC004C003 which means: that this key has been blocked. I upgrade to from windows 8.1 to 10 and never had any problems before. How could I solve out this?
