The error code 0xC004F074 appears just as you are going to activate your Windows PC. This prohibits you from completing the activation procedure and requires you to use your computer with restricted capabilities. While this might be a difficult and perplexing error message to deal with, let’s look at how you can simply resolve it.

1. Run the Windows Update and Activation Troubleshooters

Windows troubleshooting tools might be useful if you experience system problems. In this situation, we’ll look at how the Windows Update and Activation troubleshooters may assist you in resolving this activation problem.

To get started, open the Windows Update troubleshooter by following these steps:

  1. Navigate to Win Start Menu > PC Settings > Update & Security and then click Troubleshoot on the left-hand side pane.
  2. Scroll down on the right-hand side pane, click the Windows Update option, and then click the Run the troubleshooter button. Follow the on-screen instructions to finalize the process.

When your finish, run the Activation troubleshooter by following these steps:

  1. Navigate to Win Start Menu > PC Settings > Update & Security and then click Activation on the left-hand side pane.
  2. Next, click the Troubleshoot option and follow the on-screen instruction to finalize the process.

2. Re-Install the Product Key Using the Software Licensing Management Tool

If you’re seeing this issue when using an existing product key, try uninstalling and reinstalling it via the Command Prompt. To do this, use the Software Licensing Management Tool to execute a command (slmgr).

To get started, here’s how you can uninstall and re-install the product key on your Windows device:

  1. Press Win + R to open the Run command dialog box.
  2. Type CMD and then press Ctrl + Shift + Enter to open an elevated Command Prompt.
  3. Type the following command and then press Enter:
slmgr.vbs/dlv

Next, run the following command to uninstall the existing product key from your device:

slmgr.vbs /upk

When you finish, type the following command to re-install the product key:

slmgr.vbs /ipk <New_Product_Key>

Replace the New_Product_Key command with your actual product key and then press Enter to run the command. Wait for the process to complete and then restart your computer.

3. Buy a Genuine Copy of Windows or Try a Different Activation Method

If you attempt to activate a pirated version of Windows, the error number 0xC004f074 is likely to appear. The simplest method to prevent this problem is to get a genuine copy of Windows.

If you’re having this problem with a valid copy of Windows, try an alternative activation method. If you’ve been activating using a product key, consider a digital license instead. Try transferring a digital license from one of your Windows devices instead.

4. Disable the Fast Startup Feature

The Fast Startup option allows you to restart your computer faster than usual. However, this functionality may restrict certain of your PC’s capabilities. It might, for example, prevent you from accessing the BIOS/UEFI settings or even interfere with Windows updates. As a result, this feature might be the source of your device’s activation troubles.

To remedy this issue, try removing the Fast Startup functionality by doing the following steps:

  1. Press Win + R to open the Run command dialog box.
  2. Type powercfg.cpl and click on OK to open the Power Options window.
  3. Click the Choose what the power buttons do option on the left-hand side pane.
  4. In the next window, click Change settings that are currently unavailable.
  5. Uncheck the Turn on fast startup (recommended) box under the Shutdown settings and then click the Save changes button.

When you finish, restart your PC to save these changes.

5. Repair Corrupted System Files Using SFC and DISM

Corrupted system files are most likely one of the root reasons of this activation problem. In this instance, you may use the DISM and SFC tools included into your device to locate and restore any damaged system files.

To begin, launch the DISM tool by performing the following steps:

  1. Press Win + R to open the Run command dialog box.
  2. Type CMD and press Ctrl + Shift + Enter to open an elevated Command Prompt.
  3. Type the following command and press Enter:
DISM /Online /Cleanup-Image /ScanHealth

Wait for the scan to complete. From there, type the following command and then press Enter:

DISM /Online /Cleanup-Image /RestoreHealth

Restart your PC when the scan is complete.

Now you can run an SFC scan. To get started, open the Command Prompt as per the previous steps. From there, type the following command and press Enter:

sfc /scannow

When the scan is complete, close the Command Prompt and restart your PC to save these changes.

6. Temporarily Disable Windows Defender Firewall

When your Firewall stops Windows from licensing files over the Internet, you’re likely to get the 0xc004f074 Activation issue. In this instance, you might try temporarily stopping your Firewall and then reactivating it when Windows has been activated.

So, here’s how to deactivate the Windows Defender Firewall temporarily:

  1. Type Control Panel in the Windows search bar and select the Best match.
  2. Click the View by drop-down menu and then select Large icons.
  3. Scroll down and click Windows Defender Firewall.
  4. In the next window, click Turn Windows Defender Firewall on and off.

Check the Turn off Windows Defender Firewall boxes on the DomainPrivate, and Public network settings. From there, press OK to close the tab.

In addition, if you use a third-party antivirus application, you may need to temporarily disable it. However, be sure you turn it back on soon after activating Windows.

7. Contact Microsoft Support

If things don’t work out, you may want to contact Microsoft support. When you contact them, you may ask them to modify or reset your product key. Otherwise, they will provide you the greatest guidance on how to effortlessly activate Windows.

In most circumstances, you will be required to submit your PC specifications. Check and preserve your PC specifications in case they are required throughout the procedure.
