Windows 10: Trouble Activating Windows 10 on a Brand New Laptop

Would really appreciate if someone could help me out. Just bought a brand new Dell laptop, and was setting it up when I noticed a notification saying Windows 10 hasn't been activated yet. I went into settings to activate it but it gives me the error code 0xC004C008, saying that the product key was already used on another device.


I tried updating and then restarting my laptop but that hasn't fixed it. I am at a loss for what to do, because this is a brand new laptop so I don't know how the product key could've been used already.


If anyone has any insight on how to fix this, it would be greatly appreciated!

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Can't activate Windows 10 pro on brand new laptop

Hi!

I just got a brand new laptop and erased the stock windows 10 home from it to replace it with a clean windows 10 pro install, This all went fine, I deactived windows 10 pro on my OLD laptop by using slmgr /upk and the key was removed from the machine.

When I try to activate the key on my brand NEW laptop(The edition has already been upgraded to windows 10 pro) I get this error: "0XC004C003 The product key used on this pc didn't work with this edition of windows" and I cannot activate it despite this being
a valid windows 10 pro key... When I restart my laptop it will say "Couldn't reach windows activation servers" and pressing the activate button does absolutely nothing.

What I always used to do is start a live chat with microsoft if this happend and they were able to fix my issue within 2 minutes by using SLUI however, when I try to access the chat link now, it says "This chat link has been discontinued" and I cannot use
it anymore.

Can anyone help me with this?

 

Problem with activation on New Windows 10 Laptop

Hello Necrosis,

Thank you for contacting Microsoft Community.

We understand the inconvenience you have experienced.

• Is that new laptop came with Windows 10 Pre-installed?
• Is this message appearing since from the purchase?
• Do you remember any changes to the laptop made this to happen?

If you bought a new device running Windows 10, it will automatically activate when you connect your device to the Internet. If the activation servers are busy, you might need to wait a while for Windows to activate.

To check activation status, select the Start

button, then select
Settings > Update & security > Activation.

Note

• 
  In some cases, you might need to enter the Windows 10 product key that came with the device packaging, or included as a card or on the Certificate of Authenticity (COA) attached to the device.
