Windows 11 Activation Guide – Step by Step

Windows 11 Activation Guide – Step by Step

If you’ve just upgraded to Windows 11 or performed a clean installation, the next important step is activation. Activating Windows ensures that your copy is genuine, secure, and gives you access to all features. In this guide, we’ll walk you through everything you need to know about activating Windows 11 Pro or Home using a genuine license key.


Why Activate Windows 11?

Activation confirms that your Windows copy is original. Without activation, you might face:

  • A watermark that says Activate Windows.

  • Limited personalization options.

  • Security and update restrictions.

By activating, you unlock the full Windows experience and keep your device safe.


How to Check Your Activation Status

Before entering a new key, check if Windows is already activated:

  1. Open Settings (Windows key + I).

  2. Navigate to System > Activation.

  3. Here, you’ll see your activation status (Activated with a digital license / Not activated).


Methods to Activate Windows 11

1. Using a Product Key

If you bought a Windows 11 Pro key from Gominio , follow these steps:

  1. Go to Settings > System > Activation

  2. Select Change product key

  3. Enter the 25-character key you received.

  4. Click Next and follow the prompts.

2. Digital License Linked to Your Microsoft Account

If your device already had a digital license from a previous Windows 10 upgrade or earlier purchase, Windows 11 should activate automatically once you log into your Microsoft account.

3. Activation Troubleshooter

If activation fails, use the built-in troubleshooter:

  • Go to Settings > System > Activation > Troubleshoot.

  • Follow the instructions to resolve common issues.
