Lost of Product Key

Hi,

Thank you for posting your query in Microsoft Community.

• Which operating system was installed in the computer when you bought it?
• Did you receive CD of the operating system when you bought the laptop or Windows was already installed?

If you upgrade to Windows 10 from Windows 7 or Windows 8.1, you won’t receive a Windows 10 product key. Instead, Windows 10 will be activated using a digital entitlement.

The Product Key on a computer that has Windows 8 pre-installed is embedded in the BIOS on the motherboard. There is no longer any sticker with the product key.

How to find your product key depends on how you bought your copy of Windows (if Windows 10):

• 
  If you bought Windows 10 from an authorized retailer, the product key will be on a label inside the box it came in.
  
• 
  If you bought a digital copy of Windows 10 from a Microsoft website, the product key will be in the confirmation email you received after buying it or will be distributed digitally as an entitlement, in which case you won't receive a product
  key. For example, if you upgraded to Windows 10 for free, you'll receive an entitlement instead of a product key.
  
• 
  If you bought a new PC running Windows 10, the product key will be pre–installed on your PC and your PC will automatically be activated, included with the packaging the PC came in, or included on the Certificate of Authenticity (COA) attached
  to the PC.
  

Hope this information is helpful. Please feel free to reply in case you face any other issues with Windows in future.

lost windows 10 product key confirmation email for crashed windows 10 PC

Hey,

I bought Windows 10 form the cloud but I lost the email conformation with the product key.

My Windows 10 is crashed.

I was wondering how to find the Windows 10 product key that was sent to me by email.

I have a Microsoft account. I hope Microsoft has registered this product key somewhere in the cloud.

My question is how to get access to this key information.
