Fix Office Activation error 0x80070426

Error Code 0xC004F00F – What is It?

Error Code 0xC004F00F can appear during the Windows 10 installation and activation process. It is a fairly straightforward error code that occurs when a product key is entered in that is unable to be used to complete the final activation of the new operating system. This error code is most commonly related to the installation of new pieces of hardware on a machine that was already running Windows 10 at a previous time.

Error Code 0xC004F00F can also appear on other versions of the Windows software, so if you are not specifically trying to install and activate Windows 10 when this message appears, you may want to contact a qualified Windows technician to help resolve your system error, as the error code has different causes and resolution methods on other versions of the Windows operating system.

Solution

Error Causes

In some cases, Error Code 0xC004F00F will show up if you are attempting to install Windows 10 on a computer in which the hard drive has been replaced or significantly altered. It can also appear when other major pieces of hardware, like the motherboard, have been changed out.  These pieces may be changed as part of an upgrade to new or better hardware or be changed due to the malfunction of the original pieces of equipment. Because it may appear to the Windows activation servers that you are attempting to use the same product code that you have used before to activate what appears to be a new machine (even if the machine is the same one, just with some new parts), you may see Error Code 0xC004F00F arise.

Error Code 0xC004F00F can also come up if you have installed Windows 10 on your machine in the past and have already used the product key that you are attempting to use again.

Further Information and Manual Repair

Error Code 0xC004F00F most commonly appears for users who have made major hardware or software changes done on their machine. Because this error specifically arises from the Windows activation servers believing that your computer is a new one, you’ll need to get in touch with the Windows support team in order to resolve the error. From their database, they will be able to confirm that you are not using a new computer and will be able to bypass the error, allowing you to complete the Windows 10 Activation process.

If you haven’t installed or replaced any of the hardware on the computer, but are still seeing Error Code 0xC004F00F arise during your Windows 10 installation, you will still need to get in touch with the Windows support team to bypass the error code.

Calling the Windows' Support Team

When you call into the Windows support team, you’ll want to specifically have a list of the following information readily available: Which pieces of hardware have been changed out on your computer prior to the installation and activation, what method you were using to install Windows 10, which version of Windows 10 that you were attempting to install, whether it was a single-use or multiple-use license, and basic details about your PC like its make, model, and age.  You may also want to have the product key that you were attempting to use when Error Code 0xC004F00F first appeared.

By having all of this information ready and on hand ahead of time, you’ll have a greater likelihood that your error will be able to be resolved quickly and efficiently, avoiding long periods spent on the phone with customer service. Make sure that you specifically mention that you are experiencing Error Code 0xC004F00F during the Windows 10 activation process when you call into the Windows support team so that you can be connected to a representative who is equipped to help you resolve this specific problem.

Getting a Qualified Technician

If you are not comfortable in working with the Windows support team or have not been able to successfully resolve Error Code 0xC004F00F even after getting in touch with customer support, contact a qualified technician who is familiar with the Windows 10 activation process and can walk you through the things that you will need to communicate to the Windows support team in order to have them bypass or resolve the error code.

As you know, storage devices are an important part of the computer system for porting, saving, and extracting data files. And for you to differentiate between storage devices on your computer system, each one of the storage devices is labeled with a unique number referred to as Disk Signature for identification. The unique disk identifier is stored as a part of the MBR or Master Boot Record. Disk signature is used by operating systems in order to identify and set apart different data storage devices and hard disk drives in the computer for data access. These days, Disk cloning has become a regular practice in upgrading to larger hard disk drives. Drives are cloned in order to produce a similar copy to use both the original drive and cloned copy together. Moreover, lots of virtualization tools are being used to virtualize the physical hard disk drives to create virtual hard disk drives and several virtual machine clones that are created with the existing virtual hard disk drives. And since these are identical copies, chances these copies may have identical disk signatures. As a result, when you use both disks that have identical signatures at the same time you run into the Disk Signature Collision problem. This kind of problem does not often occur as the Windows system does not really allow two disks to function simultaneously when they have the same disk signature. When you encounter a Disk Collision problem in your Windows 10 computer, you may see the following error messages:

• The boot selection failed because a required device is inaccessible
• The disk is offline because it has a signature collision
• This disk is offline because it has a signature collision with another disk that is online

You can fix the disk collision problem by changing the disk signature which you can achieve using the command line utility diskpart in Windows PowerShell or Command Prompt or using Windows Disk Management utility. To fix the disk collision problem, you can make use of the command-line utility called diskpart in Windows PowerShell or Command Prompt to view and change the signature, or can make use of Master Boot record in the Windows Registry. You can also make use of Windows Disk Management Utility to change the signature. Simply follow the given options below to change the disk signature either way.

Option 1 – Change Disk Signature via Diskpart

• Type “command prompt” in the Windows Search bar and then right-click on the related search result and select the “Run as administrator” option.
• After that, type the “diskpart” command and hit Enter to open Diskpart.
• Next, type the “list disk” command to display all the disks available in the system.
• Next, take note of the problematic disk number with the status Offline from the list and then type the “Select disk x” command where x is the offline disk to select the offline disk. For instance, if you type “select disk 1”, it will display the “Disk 1 is now the selected disk” message.
• Now type the “Uniqueid disk” command to display the disk signature and to change the disk’s signature and set the disk online, type the “unique disk ID= (New signature)” where (New signature) is the new ID in hexadecimal. For instance, you can set the new id as “unique disk ID= 1456ACBD”.

Note: If you have given the wrong format ID, the command prompt will display the following error:

“The specified identifier is not in the correct format. Type the identifier in the correct format: in hexadecimal form for an MBR disk or as a GUID for a GPT disk.”

• After you’re done, the disk will be online, and then restart your computer.

Option 2 – Change Disk Signature via Disk Management Utility

• Tap the Win + R keys to open the Run dialog box and then type “diskmgmt.msc” and hit Enter or click OK to open Disk Management.
• Next, right-click on the disk that is marked as Missing or Offline.
• After that, select the Online command from the drop-down menu.
• Then from the selecting option Online, Windows will generate a new disk signature.
