Windows 7 Online Activation Error 0xC004C008

Yesterday, I was installing Windows 7 on a friend’s computer, and I got error code 0xC004C008 when I attempted to activate over the internet.  I had never seen that error before, but after some research, it is a common error that can be easily resolved (if you don’t mind automated phone systems).

Microsoft says that error code 0xC004C008 can be caused by a number of things, such as your computer’s hardware recently changed, Windows 7 was reinstalled on the same computer, your Windows 7 product key was transferred from another computer, or the ‌Windows 7 product key that you’re trying to use has already been used on the maximum number of computers that your license allows.

Here is the work around. 

  • If you don’t already have the Activation Window open, click on the start menu, right click on “Computer” and select “Properties”, and then click on “Activate Windows now”.
  • Click “Show me other ways to activate.”
  • Type your product key in the boxes provided (your cursor will automatically advance)
  • Click “Use the automated phone system” and then select “Next”
    • You might be prompted by UAC to continue or enter your administrator password.
  • Select the country that you live in from the drop-down list, then select “Next”.
  • Call the number that is provided for you.
    • An automated system will guide you through the activation process, if there are any problems, the automated system will transfer you to a Microsoft Activation Representative, and they will take it from there.
  • Next either the automated phone system, or the representative will give you a confirmation ID, as they are telling you the confirmation ID, type it into the boxes provided (your cursor will automatically advance).
    • Make sure to stay on the line until the activation is successful. If for some reason, the activation is not successful, the automated phone system can help you, or they will transfer you to a Microsoft Activation Representative who will get the issue resolved for sure.
