The following instructions can assist you in resolving the 0xc004f063 activation error.

Windows 7 OS has been experiencing this error since 2010 or even earlier, and it’s known as 0xC004F063, an old Windows Activation and Validation error[1]. In spite of the fact that the problem has been known for more than ten years, tech forums keep receiving requests for solutions.


Why does 0xc004f063 Windows activation error occur?

Why does 0xc004f063 Windows activation error occur?

Many factors can cause Windows Activation error 0xC004F063 to occur. The most common cause of this activation error is third-party software colliding with the OS components, such as Daemon Tools, Alcohol 120%[2], or similar. But that’s rare.

In a legitimate and approved license key activated operating system, the 0xc004f063 system error can occur. Reasons for this include:

Third-party software conflicts: Although rare, some third-party programs such as Alcohol 120% and Daemon Tools can conflict with the operating system and compromise the license key.

Window problems: Installed Windows updates may contain activation errors that prevent the operating system from obtaining a license. This usually results in the error message “The BIOS license required for Windows BIOS – 100xc004f063 is missing”. Licensing restrictions related to Windows errors can be easily fixed by running automatic recovery of Windows activation errors.

Damaged system files: Damaged system files may prevent the operating system from checking for activation. If this is the case, you can fix it with the built-in tools: Windows System File Checker (SFC) and Deployment Image Servicing and Management (DISM).

BIOS mismatch: If you reset an already activated PC and try to activate another version of Windows (such as Home, Pro, or Enterprise) while the old key is still stored in the BIOS, the 0xc004f063 error will be removed. The SLMGR utility can help solve this problem.

Server problem: Your license key may not be recognized by MS servers. Contact Microsoft support for help with this problem.


To fix Windows 10 activation error 0xc004f063

Updated: February 2024

We highly recommend that you use this tool for your error. Furthermore, this tool detects and removes common computer errors, protects you from loss of files, malware, and hardware failures, and optimizes your device for maximum performance. This software will help you fix your PC problems and prevent others from happening again:

  • Step 1 : Install PC Repair & Optimizer Tool (Windows 10, 8, 7, XP, Vista).
  • Step 2 : Click Start Scan to find out what issues are causing PC problems.
  • Step 3 : Click on Repair All to correct all issues.


To fix Windows 10 activation error 0xc004f063

Run the activation troubleshooter (Windows 10 only).

Consider using your system’s automatic repair feature first. When Windows detects a known scenario, it is able to use several different automatic repair strategies.

The Windows activation diagnostic tool should be able to automatically fix the problem if it is caused by any license restrictions. As part of this integrated tool, you can select a repair strategy that will fix your activation problem automatically if that strategy already covers the issue.

IMPORTANT: This method is applicable only if the problem occurs in Windows 10. If the 0xc004f063 error occurs on an older version of Windows, go to the following method described below.

Many users who reported experiencing 0xc004f063 activation errors have reported solving it by running the activation program and restarting their computers. Since then, they have been successful in activating the license key.

An activation error recovery guide is provided here:

  1. You can open the Activation tab in Settings by pressing Windows + R, then typing “ms-settings: activation” and pressing Enter.
  2. The Troubleshooting button is located at the bottom of the Activation tab’s right-hand pane.
  3. Once the utility has started, wait for it to run a full scan of your system for errors. If the utility finds problems, it will provide a repair strategy, which will then need to be applied to your system.
  4. If the problem continues, repeat the process described below. Upon restarting your computer, wait for the next startup sequence. Once the next startup sequence is completed, follow the next method.

Activate Windows with SLMGR

The problem is likely caused by the fact that your BIOS is still using your Windows security key if you see error 0xc004f063 when trying to activate your PRO key. When a user resets a pre-activated computer, it occurs quite often.

No matter which activation key you try to activate, your operating system will try to activate it using the key stored in the BIOS if this scenario applies. Here’s how to override the wrong activation key if you find yourself in this situation: Enter the following commands on the extended command line to override the wrong activation key:

  1. When the “Run” dialog box appears, open it, enter “cmd” in the text box, and then hold down the Ctrl and Shift keys. Click Yes when the User Account Control (UAC) window appears.
  2. The following commands can be used on the extended command line to change your license key. Enter each command after it is completed.
  3. A special Windows key is created with slmgr/ipk
    slmgr / ato
  4. Note: Keep in mind that *windows-key* is reserved space only. To complete this process, you must replace it with your license key.
  5. Restart your computer after the process is completed to determine if the changes are effective.

Continue to the next method below if you are still unable to activate Windows with a valid license key.

Performing SFC and DISM scans

An activation error of 0xc004f063 can be caused by a type of system file corruption, which is one of the most common causes. Usually, this problem occurs because your operating system cannot validate an activation process that has been affected by a critical problem.

Using built-in utilities that fix local errors and corrupt operating system files is the most effective way to solve this issue if this scenario applies to you. A deployment image servicing and management tool such as DISM (Deployment Image Servicing and Management) or a System File Checker can perform this function, but in different ways.

While SFC has a better ability to fix logical errors, DISM has a better ability to find corrupted subprocesses and replace them, which is due to its dependence on WU (Windows Update).

Here are the steps you need to take in order to fix error 0xc004f063. If you do not already have a clear understanding of how to fix this error, we recommend you use both utilities.

  1. You can open the command prompt by pressing Ctrl + Shift + Enter after pressing Windows + R to open the “Run” dialog box.
  2. Note: When you see the UAC (User Account Control) prompt, click “Yes” to grant administrator access.
  3. The DISM command can be executed by entering the following commands sequentially in the expanded CMD window and pressing Enter.
  4. ScanHealth /online/cleanup-image/dism.exe
    ScanHealth /online/cleanup-image/dism.exe recovery
  5. Note: Before starting this procedure, make sure that your internet connection is stable. This is important because DISM uses WU to download clean files that are used to replace damaged items. Just so you know what the commands do: The first (health scan) scans the system for inconsistencies and the second (health recovery) starts the recovery process.
  6. Whenever the SFC scan starts, you should wait for the process to finish before rebooting your computer. Finally, reopen the high PDC prompt and enter the following command:
  7. sfc / scans.
  8. Note: Under no circumstances should this process be interrupted before it is complete (even if it freezes for a few minutes). If you do, it will compromise your system and more logical errors may occur.
  9. Check your computer for a resolution after you finish the second system file scan by restarting it.

Go to the next method if error 0xc004f063 persists after following the above steps.

Contacting Microsoft Support

It is best to contact Microsoft support if the 0xc004f063 error occurred even after you used one of the methods listed above.

Toll-free numbers specific to your region make this easier, but if you have any questions, contact a Microsoft representative.

It may take a few hours for a live agent to respond to your request depending on your region.

The activation will be performed remotely once you’ve successfully engaged the person and answered a few security questions.
