Let’s delve into the distinction between a product key and an activation code:
Product Key
-
A product key is a unique alphanumeric code provided during the installation of Microsoft software (such as Windows or Office).
-
It serves as a license key that validates your ownership of the software.
-
Product keys are typically 25 characters long and are used during the installation process.
-
When you enter a valid product key, it unlocks the full functionality of the software.
-
Think of it as the “key” that grants access to the software.
Activation Code
-
An activation code (also known as an activation key) is used to activate the software after installation.
-
Activation ensures that the software is genuine and legally licensed.
-
Unlike a product key, which is entered during installation, the activation code is applied after installation.
-
Activation codes are often linked to a specific hardware configuration or user account.
-
They verify that you have a valid license to use the software.
In summary, a product key is used during installation, while an activation code is used to activate the software afterwards. Both are essential for ensuring a legitimate and functional software experience.
Tip: For Windows 10/11, if you encounter a situation where your product key is shorter (20 characters), don’t worry, you can reinstall Windows 10/11 without needing a product key. Once your PC is connected to the internet, Windows 10 will self-activate based on your digital entitlement stored on Microsoft’s activation servers.
