Windows 2008 Server Activation Error 0xc004c003 RRS feed

  • Question

  • I have tried to activate my Windows Standard 2008 64 bit and gives this error 0xc004c003; Windows determined that this key is already in use. I was sent another Package with a different MAK and it does the same thing. You go to Properties and Change Windows Key to activate and it still does same thing. I need help urgently.

  • Hi,

     

    This indicates the MAK is already in use or is blocked.

     

    Please contact Microsoft Activation Center for direct assistance.

  • To fix the problem, buy a product key for each one of your devices to activate Windows on them. If you're using Windows 10, you can buy Windows from the Microsoft Store: Select Start > Settings > Update & Security > Activation
