This error code indicates that Key Management Service or KMS couldn’t be contacted while the activation process is underway. The user is unable to use her computer and finds the following message:

Windows is unable to reach your company’s activation service. Please connect to your corporate network. If you are connected and continue to see the error, contact your system administrator. You can also click on the error detail to find the exact error. Error code: 0xc004F074.

A rather well-known issue, this error first emerged when Windows 10/11 was released back in 2015. Microsoft dutifully released a patch and fixed this bug. Unfortunately, the error continues to reappear along with the Cumulative Windows Updates.

In general, error code 0xc004f074 emerges due to accessing an invalid or compromised copy of Windows, which might cause harm on the computer. This version can come from pirated software sites, which are dangerous and can cause permanent system damage. This is why the user is recommended to download a valid version from the official website, and then activate the key there so no activation issue crops up.

If, however, you are confident that you downloaded a legitimate Windows 10/11 update but still get the error, then learn how to fix the problem manually.

Ways to Fix Error Code 0xC004F074

Using the slmgr.vbs Command

  3. When you see a prompt, click the Yes button to proceed.
  4. Once in Command Prompt, type in the following command: slmgr.vbs –ipk YYYYY- YYYYY – YYYYY – YYYYY – YYYYY. In the code, replace the Y letters with your product key number. The product key should also contain 25 numbers. Hit Enter.

Running the Update Troubleshooter

It makes sense to run the update and activation troubleshooters since the error takes place shortly after installing the latest updates. To do this, simply go to Settings > Update & Security > Troubleshooter. From there, choose Windows Update. Run the troubleshooter as usual.

Does the issue persist? Then continue with the Windows 10/11 Activation Troubleshooter. Navigate to Settings > Update & Security > Activation > Troubleshooter. Wait for the process to complete. Afterwards, reboot your machine to check if the error code is still present.

Running an SFC Scan

You can also take advantage of System File Checker (SFC) to fix the error. It will check if there are corrupted system files that could be leading to the issue. Here are the steps:

  1. Click the Windows + X keys.
  2. Choose Command Prompt (Admin).
  3. Next, type in sfc/scannow and then press Enter. This will start the System File Checker.
  4. Wait for the process to complete in the next few minutes.
  5. Restart your computer and try once again to activate Windows 10/11.

Contacting Microsoft Support

If the problem cannot seem to let up, we suggest that you contact the Microsoft Customer Support staff to get further assistance. You can tell them more about the error and even ask for your product key to be changed. There are cases where using the product key multiple times results in getting blocked by the server. Here, the support team can help reset the product key.
