Further Information and Manual Repair

Both of the methods we have available for manually fixing the 0xC004C003 Error Code will require you to reset your PC and this could mean that your data will be lost. Make sure to backup any important files and data before starting any of the methods that we have listed below.

Method One is the quickest option on this list and should take less than thirty minutes. Method Two can take multiple hours depending on how slow your PC hard drive is.

 

Method One:  Reset Windows 10

 

Method One doesn’t require you to reinstall Windows 10 again completely but it does mean that you’ll need to reset your data and essentially start from scratch. To perform a reset, open the Start Menu and click the settings (gear) icon. Next, use the search field to search for Recovery Options. Now click the ‘Get Started’ box underneath the ‘Reset this PC’ option. Once the reset has been completed you may be able to activate Windows 10 without any errors.

 

Method Two:  Upgrade from Windows 7, 8, or 8.1

 

Unfortunately Method One may not fix the issue for everybody. If the first method cannot resolve the problem, your next best bet is to try Method Two. For this method you will need to reinstall your original operating system (Windows 7, 8, or 8.1) and then upgrade to Windows 10 again. To do this, you’ll need to find the original Windows installation disc for your version of Windows. You can then install the older version of Windows as a fresh install on your PC. After it has installed you’ll need to manually update to the latest version of Windows. Once your PC has finished updates, you’ll be able to click the Windows 10 notification to upgrade for free.

Because of the vast number of updates, this process can take up to an entire day to complete.
