Activation problem

Question

Hello, 

last time no one responded. Why? 

I Have issue with activation. It keeps saying code 0xC004C008.

But the problem is i don't have activated my Windows 10 Pro on other computer, only on this one.

Please tell me what is the problem.

Answer 1

License code that i can activate by installing from 8.1 pro to Win 10 Pro with Instalation Media

Answer 2

How do i know from that application ProducKey if my bought product key is working or not?  

When i had it installed on my laptop (its now Win 8.1 not Win 10) the code worked.

I Got that problem with activation after i signed in my MS account.

I Would tell you the product key and product ID but it would end really bad.

Hi Kristian. I'm Greg, an installation specialist and 9 year Windows MVP, here to help you.

How was Windows 10 originally Activated on the PC? Did it come preinstalled from Factory, was it Upgraded with free or paid Upgrade, or was it a retail copy and license?

For Upgrade when you first upgraded and it activated it assigned a permanent Digital License to the PC in Microsoft Activation Servers so you can reinstall any time and in any way you want as long as you reinstall the licensed version. Skip the key during install and it should reactivate soon after going online.

If you change hardware follow the steps here: https://support.microsoft.com/en-us/help/20530/.... As long as the original license that was upgraded was not factory or builder's OEM it should allow it to move. If you sign in with the MS Account that is linked to the Digital License and run the Troubleshooter it should automate this, and even if OEM may make an exception if all else is correct.

Factory installs have the Product Key embedded in BIOS or UEFI firmware and should activate themselves, but you can check for the key by installing ProducKey and look for OEM-BIOS key: http://www.nirsoft.net/utils/produkey-x64.zip

Retail keys must be reinserted for reinstalls during install or in Settings.

All methods of activation are converting to Digital Licenses to make it easier to change hardware, however Factory and Retail Product Keys will still reactivate Windows if the DL doesn't.

What is the Status and Edition shown at the top of the page at Settings > Update & Security > Activation?

Run the Activation Troubleshooter at Settings > Update & Security > Activation.

If this fails you can contact Microsoft Support, asking for Activation help, then keep asking for an agent. https://partner.support.services.microsoft.com/...

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

Hi,

What license do you have - box, OEM? Did you make any changes in hardware?

Answer 5

Hi Kristian

Was Windows ever activated on that PC, or are you trying to activate Windows 10 on that PC?

Do you have your Windows 10 Product Key?

Click your Start Button, type cmd then right click Command Prompt and choose 'Run as Administrator'

Run or paste this command and hit Enter:

slmgr.vbs /dlv
