Issue: How to fix Windows activation error 0xc004c008?

Hi, guys. Could you please tell me why I am getting an error code 0xc004c008 when installing Windows 10. I have a valid product license key, so I have no idea why Windows 10 cannot be successfully be activated. Please advice.

Solved Answer

The Error Code 0xc004c008 is a known Windows problem. People can come across this error on Windows 7, 8 , 8.1, and 10, but the oldest version (Windows 7) is not very likely to return this error anymore. Usually, people come across this bug when trying to install Windows 8 or 10 more than once.

This bug check means that the product key[1] you are using has already been used on another PC, or it’s being used on more devices than the Microsoft Software License Terms[2] allow. If you are installing Windows OS on the same device, the same product activation code will be approved as many times as you need. However, in case your PC crashed and you changed it to another one, the same license key won’t fit, which is why you may get the error code 0xc004c008.0xc004c008 error

The problem may be triggered by the changes of some hardware components[3] either. For instance, if you changed a motherboard, RAM or hard drive, Microsoft may treat your device as a new one and reject the license key that you own.
In case your Windows 10 license expired or it’s no longer valid because you’ve changed the PC or reached the limit of devices that can run using the same product license key, you will have to buy a new Windows product activation code from Windows Store:

  • Press Windows key + I to open Settings.
  • Select Update & Security and open Activation tab.
  • Select Go to Microsoft Store. Once there, follow the on-screen instructions to by Windows 10 license.

Purchase new license

Prevent websites, ISP, and other parties from tracking you

Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down. You can also bypass geo-restrictions and view such services as Netflix, BBC, Disney+, and other popular streaming services without limitations, regardless of where you are.

A VPN is also crucial when it comes to user privacy. Online trackers such as cookies can not only be used by social media platforms and other websites but also your Internet Service Provider and the government. Even if you apply the most secure settings via your web browser, you can still be tracked via apps that you are connected to the internet. Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speed.

Therefore, to stay completely anonymous and prevent the ISP and the government from spying on you, you should employ Private Internet Access VPN. It will allow you to connect to the internet while being completely anonymous, prevent trackers, ads, as well as malicious content. Most importantly, you will prevent the illegal surveillance activities that NSA and other governmental institutions are performing behind your back.


Recover your lost files quickly

Unforeseen circumstances can happen at any time while using the computer: it can turn off due to a power cut, a Blue Screen of Death (BSoD) can occur, or random Windows updates can decide to reboot the machine when you went away for a few minutes. As a result, your schoolwork, important documents, and other data might be lost.

Additionally, you might also be attacked by malware that can corrupt your Windows or encrypt files with a robust encryption algorithm, and ask for a ransom in Bitcoin for the decryption tool. Cybercriminals might not deliver what they promised, however, so it is better to attempt alternative file recovery methods that could help you to retrieve at least some portion of the lost data.

Data recovery software is one of the options that could help you recover your files. Once you delete a file, it does not vanish into thin air – it remains on your system as long as no new data is written on top of it. Data Recovery Pro is recovery software that searchers for working copies of deleted files within your hard drive. By using the tool, you can prevent loss of valuable documents, school work, personal pictures, and other crucial files.
