Understanding Your Windows 11 Activation Method
Before you activate, it’s helpful to understand the primary activation methods Microsoft uses to verify that your copy of Windows is genuine.
What is a Product Key?
A Windows Product key is a 25-character code used to activate the operating system. It’s the proof of purchase that confirms you own a genuine license for Windows 11.
You typically get this key when you buy a retail copy of Windows 11 or a new computer that includes it. To activate Windows 11, you will need a valid product key.
What is a Digital License?
A Digital License (also called a digital entitlement) is a more modern method of activation where the license is linked directly to your computer’s hardware and your Microsoft Account.
You usually have your Windows 11 activated with a digital license if you are upgrading from Windows 10 for free, bought Windows 11 from the Microsoft Store, or are a Windows Insider.
Key Distinction: OEM vs. Retail Licenses
It’s also crucial to know what kind of license you have for activating Windows.
- OEM (Original Equipment Manufacturer) License: This license is pre-installed by the PC manufacturer and is tied permanently to that device’s motherboard. It cannot be transferred after major hardware changes.
- Retail License: This license is one you purchase separately. Its main advantage is that it can be transferred from one computer to another, which is essential if you plan to reinstall Windows 11 on a new machine.
How to Activate Windows 11/10 After Installation (via Settings App)
Windows 11 Product Key Activation
This is the most direct method if you have your 25-character key and Windows 11 is already running.
To access the main Windows 11 activation panel, go to Settings > System > Activation.
Click the “Change” button next to “Change product key“.
A new window will appear. Carefully enter the product key and click Next.
Windows 11 will then connect to Microsoft’s servers to verify the key and activate your system.
Windows 10 Product Key Activation
To access the main Windows 10 activation panel, go to Settings > Update & Security > Activation.
Click the “Change product key” button.
A new window will appear. Carefully enter the product key and click Next.
Windows 10 will then connect to Microsoft’s servers to verify the key and activate your system.
Using a Product Key to Upgrade Your Windows 11 Edition
This same straightforward process can be used to upgrade your edition of Windows 11.
For instance, if you are running Windows 11 Home and enter a valid product key for Windows 11 Pro, the system will begin an upgrade process to unlock the professional features before completing the activation.
