Why do I get error code 0xc004c008 when I install Windows 10. I have a valid product license key, so I don’t know why Windows 10 can’t be activated successfully. Please give me advice.

Error code 0xc004c008 is a known Windows issue. People can get this error on Windows 7, 8, 8.1, and 10, but the oldest version (Windows 7) can no longer return this error. Usually, people get this error when trying to install Windows 8 or 10 multiple times.

Checking for this error means that the essential product you are using is already in use on another computer or that it is being used on more devices than the Microsoft Software License Terms allow. If you are installing Windows OS on the same device, the exact product activation code will be accepted as many times as you need. However, in case your computer crashes and you changed it to another server, the same license key will not match, which is why you might get error code 0xc004c008.

The change of some hardware components may trigger the problem. For example, if you change your motherboard, RAM, or hard drive, Microsoft might treat your device as a new device and deny the license key you own.

Suppose your Windows 10 license expires or is no longer valid because you changed computers or reached the limit of devices that can run using the same product license key. In that case, you will have to purchase an activation code New Windows product from the Windows Store:

  • Press Windows key + I to open Settings.
  • Select Update & Security and open the Activation tab.
  • Select Go to Microsoft Store. Once there, follow the on-screen instructions using Windows 10 license.
