How to Fix Windows 8 Non-Core Edition Activation Error
If you are trying to activate Windows 8 non-core edition, you may encounter an error message that says:
Error: 0xC004D302 On a computer running Microsoft Windows non-core edition, run 'slui.exe 0x2a 0xC004D302' to display the error text.
This error can be caused by various factors, such as using an incorrect or invalid product key, having corrupted or missing activation files, changing your hardware configuration, or having issues with the Microsoft activation servers. In this article, we will show you some methods to fix this error and activate your Windows 8 non-core edition successfully.
Method 1: Check your internet connection and try again later
One of the possible reasons for this error is that your internet connection is not working properly or there is an outage with the Microsoft activation servers. To rule out this possibility, make sure your internet connection is stable and try to activate Windows 8 non-core edition again after some time. Sometimes, the error may resolve itself after a while.
Method 2: Make sure the product key is correct
Another possible reason for this error is that you are using an incorrect or invalid product key to activate Windows 8 non-core edition. To eliminate this possibility, recheck the product key and make sure it matches the edition of Windows you have installed on your computer. You can also sign in with the Microsoft account associated with your product key to verify its validity.
Method 3: Run Windows Activation troubleshooter
Windows 8 has a built-in troubleshooter that can help you diagnose and fix common activation problems. To run the Windows Activation troubleshooter, follow these steps:
Press the Windows key + I to open the Settings app.
Navigate to System > Activation.
Click on the Troubleshoot link and follow the on-screen instructions.
The troubleshooter will scan your system and try to fix any issues that may prevent you from activating Windows 8 non-core edition.
Method 4: Install the key on the KMS host
If you are using a Key Management Service (KMS) host to activate Windows 8 non-core edition, you need to have a specific product key called a Generic Volume License Key (GVLK). This key is different from the one you use to install Windows 8 non-core edition. If you have not installed the GVLK on your KMS host, you may see this error. To install the GVLK on your KMS host, follow these steps:
Open an administrative command prompt on your KMS host.
Run the following command and then press Enter: slmgr /ipk
Replace with the GVLK for your edition of Windows 8 non-core edition. You can find a list of GVLKs for different editions of Windows here: Key Management Services (KMS) client activation and product keys.
Wait for the confirmation message that says \"Product key installed successfully\".
After installing the GVLK on your KMS host, try to activate Windows 8 non-core edition again on your client computer.
Method 5: Rebuild the activation token file
The activation token file is a file that stores information about your activation status. If this file is corrupted or missing, you may see this error. To rebuild the activation token file, follow these steps:
Open an administrative command prompt on your client computer.
Run the following command and then press Enter: net stop sppsvc
This will stop the Software Protection service.
