If the Error Code 0xC004C770 popped up on your computer during your activation of the Windows 10 software, don’t worry. This is a fairly common error, especially for people who own more than one computer upon which Windows 10 is installed and activated. The gist of this error code is that the product key that you have entered has already been claimed or used on a different computer. Because there are limitations on the number of computers that can use any given license activation code or product key, this error code can arise when you have exceeded that limit. If you have a single-use license and have already entered the particular product key onto another machine, you may see this error come up during activation.
Both Error Code 0xC004C770 and Error Code 0x803FA071 arise from the same problem and the same steps can be used to resolve both error codes.
Error Code 0xC004C770 is likely to appear on your screen during activation of Windows 10 if you or anyone else in your organization have already entered in the product key used on another computer. If you have a multiple-use license, the product key that you are entering may already have been used for the maximum number of computers allowed under that license.
