Windows 10 product key

I bet you know what is Windows product key right? No? Basically, it is how to ensure the copy of Windows that is installed on your computer is genuine. When you installed and activated the Windows, the key will be sent to Microsoft for verification. If it is not in their record, the activation will be denied.


Nowadays, the majority of computers or laptops are already pre-installed with Windows copy. The product key for this kind of Windows copy is commonly referred to as an OEM key, OEM product key, or OEM license.

On the other hand, if you purchased a copy of Windows, then you manually installed and activate it. This is commonly referred to as Windows retail license. This is the key that you need to keep safe, in case you need it for future installation.

Note: The following methods will show you how to find a Windows 10 OEM key and retail license. This method works on Windows 10 and above.

    • OEM Key: This is the OEM key

For retail license, better to save it somewhere for your future installation. And please remember to not share this key with anyone.

However, for the OEM key, you probably don’t need it as it is already tied to the hardware. Whenever you installed a copy of Windows, it will automatically detect the OEM key and activate your Windows.
