If you have a Windows 11 DVD/USB purchase either for a new system, or for an upgrade on an older PC, and it is asking to be activated after you get loaded into Windows 11, here is how to activate that license once you have Windows installed.
Here is how to activate a new Windows 11 license:
1. Locate your Windows 11 packaging. Within the packaging of the DVD or USB, you will find a multi-colored sticker that may say 'Windows 11 Home/Pro' (depending on what was purchased).
Some of the activation key will be covered for security reasons. The full key will need to be revealed. On this sticker, gently scratch off the grey/silver Microsoft portion with a coin to reveal the full product key.
2. To activate this key on your Windows 11 system, right-click on the Start button, typically found at the lower left corner of the screen, and from the list of options, click on Settings.
3. From the Windows Settings page, from the list of categories, navigate to System.
4. Once you're in System Settings, scroll down and locate Activation.
5. On this screen, click on Change next to where it shows 'Change product key'
6. On the Enter a Product Key window, type in the product key sticker.
Entering dashes will be done automatically so do not include those after each set of letters and numbers. You should have a total of 25 characters. If you have less than that, double-check that you gently scratched off all the silver material and revealed the entire key.
7. Click on Next to complete activation and you're all set!
