    I'm experiencing the same problem like you, upgraded my windows 7 professional PC since july 29th and can't activate it.
    Product key blocked. Error code: 0xC004C003, several calls to microsoft haven't helped all i keep getting from the agents on phone is to wait 24-48 hours.
    It will be two weeks on 12th august still no resolution by microsoft
