An OEM license is used by device manufacturers on devices that they manufacture. Examples of these devices are desktops, laptops, and smartphones. Take note that you cannot reactivate Windows on your device if you installed it with an OEM license.

2. Retail Windows License

This is a license key that you purchase from an accredited local store or an online seller.

3. MAK Volume License

This type of license is widely used by large businesses, corporations, government sectors, and educational institutions. You cannot activate this license for personal use.

If you want to know the type of product key you are using, simply open PowerShell via the WinX menu and type the slmgr /dli command.

Fix #1: Use the Command Prompt

Here’s what you should do:

  1. Press the Win + X shortcut to access the WinX menu.

  6. Hit Enter to execute the code and click OK to confirm.
  7. Once done, restart your computer and try activating Windows 10/11 once again.

Fix #2: Use the Windows 10/11 Activation Troubleshooter

Windows 10/11 has a built-in tool that you can use when you encounter problems with your activation key. You can use this tool to fix the error 0xc004f025, too. It’s pretty straightforward. Simply follow these steps:

  1. Log in to your computer using an administrator account. If you don’t have one, create one manually.
  2. On the main Windows screen, click the Start button and select Settings.
  3. In the window that appears, choose Update and Security and click Activation.
  4. Navigate to the right pane of the window and click the Troubleshoot link.
  5. At this point, the troubleshooter will begin scanning your system for any faults and repairing them. Wait for the process to complete before performing a restart.

Fix #3: Check the Product Key

In some cases, the error code 0xc004f025 appears because of an incorrect product key. For this, simply re-confirm the product key by following these steps:

  1. Launch the Settings window by pressing the Win + I shortcut.
  2. Go to the Update and Security section and click Activation.
  3. Navigate to the right pane and find the Update product key section.Check the Product Key
  4. Click the Change Product Key link.
  5. Now, type the genuine activation key and select Next to proceed.
  6. Follow the on-screen prompts to complete the process.
  7. Once done, restart your device and see if the error code still shows.

Fix #4: Perform a Clean Install

If the solutions above don’t fix the activation error, the operating system you are trying to install may have become corrupt. And in that case, you need to perform a clean install of Windows 10/11 using the Media Creation Tool.

Below is a detailed guide on what to do:

  1. Insert your Windows installation media and restart your computer.
  2. While the BIOS is loading, press any function keys.
  3. You will now see a new screen. Click Next to proceed.
  4. And then, click the Install Now button.
  5. Next, type the product key and agree to the license terms.
  6. Continue by clicking Next.
  7. Select the Custom install Windows only (advanced) option.
  8. Delete the previous drive partition and reallocate its memory space.
  9. Finally, enter your region, preferred language, ID, and other required information to verify the setup process.
  10. Restart Windows. Hopefully, the activation error code is gone.

Fix #5: Reactivate Windows

Have you just performed a major hardware change? Then it is likely causing the activation error 0xc004f025 to appear. Users who replaced their motherboards and RAMs reported that they had seen the error after such an upgrade. So, if you have performed similar changes, reactivate Windows 10/11 using the same genuine activation key.

Fix #6: Remove Any Rearm Dependencies

Another reason why you might be seeing the error code is that there may be a problem with how Windows saves and maintains rearm dependencies associated with your current license key. What this means is that there may be traces of the rearm files from a previous license key.

In this scenario, you can skip the reactivation timers using the Registry Editor. And then, run the rearm command and then rename the main SLMGR script to force Windows to generate a new instance.

Below is a guide on what to do:

  1. Press the Win + R shortcut to launch the Run dialog box.
  2. Type regedit into the text box and hit Enter to launch the Registry Editor.
  3. Once the Registry Editor opens, navigate to this location: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform.
  4. Navigate to the right pane of the window and double-click on the SkipRearm file.
  5. Go to Edit D-Word and set the Base value to Hexadecimal. Also, set the Value data to 1.
  6. Click OK to save your changes.
  7. Once done, close the Registry Editor.
  8. Now, press the Windows logo key + R combo to launch the Run utility.
  9. Type cmd into the text field and press the Ctrl + Shift + Enter shortcut to launch an elevated Command Prompt.
  10. If prompted, click Yes to grant administrator privileges.
  11. Type the slmgr rearm command and hit Enter to execute it.
  12. Once you see the success message, open File Explorer and navigate to this location: C:\Windows\System32.
  13. Next, use the search function to find the slmgr.vbs file.
  14. When you find it, right-click on it and rename it. Change the .vbs extension to .old. Doing this will force your operating system to disregard the file and create a new one instead.
  15. Restart your computer and see if the error code is gone.

Fix #7: Clean Your PC

Though it rarely happens, junk and unwanted files may mess with the activation process. As a result, you may see an error code like 0xc004f025.

To get rid of unnecessary files and PC junk, we suggest using a PC repair tool like Outbyte PC Repair. This tool will scan your system for temporary and cache files that are only doing more harm than good to your system’s health. Once the tool finishes the scan, it will suggest removing them to keep your system running error-free.

It will also help if you run a malware scan to ensure no malware entities are hiding on your system. For this, you can use the built-in Windows Defender app or any third-party tool of your choice.

Fix #8: Seek Help from Microsoft

If you are still getting the same error code, the only viable fix left right now is to get in touch with a Microsoft support agent. Ask them to activate your operating system on your behalf.

Seek Help from Microsoft

You can schedule a call with one of Microsoft’s agents or choose to call a toll-free hotline. Once you speak with a Microsoft agent, expect to be asked a few questions. They do this to confirm if you are really the owner of the license key.

What Happens If You Don’t Activate Windows?

Because of the activation error, many of you may already be discouraged to continue activating Windows. Well, don’t be. Although you can still utilize Windows, you cannot use its features to their maximum potential if the OS is not activated.

Wrapping Up

With everything we have discussed above, it is safe to assume that the Windows 10/11 activation error code 0xc004f025 is not that hard to fix. In fact, you can easily resolve it using the fixes we have enumerated above. All of them are very easy to perform. As long as you follow the steps carefully, for sure, the error code will be gone in no time.

We’re not suggesting trying all the fixes above. Just find the fix that you think best applies to your situation. For instance, if you can’t access the login screen, consider using the Command Prompt to resolve the error. Otherwise, you have other fixes at your disposal, including reactivating Windows, performing a clean install, using the Windows 10/11 activation troubleshooter, and checking the product key. If all else fails, you can get in touch with Microsoft’s support team and let them activate your operating system for you.
