How to Activate Windows 11 (Legal Ways & Product Keys)

After installing Windows 11, you must activate it to unlock all features like personalization, updates, and security enhancements. Activation can be done using a product key, digital license, or linked Microsoft account.

Here are all the legal methods to activate Windows 11 step by step.

1. Method 1: Activate Windows 11 with a Product Key

If you purchased a genuine copy of Windows 11, you should have a 25-character product key (XXXXX-XXXXX-XXXXX-XXXXX-XXXXX).

  3. Click Change product key.

  4. Enter your 25-character key → click Next → Activate.

A digital license is tied to your Microsoft account and doesn’t require entering a key.

When do you get a digital license?

  • Upgrading from Windows 10 (genuine).

  • OEM devices (laptops/PCs pre-installed with Windows 11).

Steps:

  1. Sign in with the Microsoft account linked to your license.

  2. Open Settings → System → Activation.

  3. If a license is detected → Windows will auto-activate.

  4. If not, click Troubleshoot → select I changed hardware on this device → choose your PC.

✅ Useful when reinstalling Windows or after replacing hardware.

3. Method 3: Activate Windows 11 During Installation

  1. While installing Windows 11, setup will ask for a product key.

  2. Enter the valid key → activation will be automatic after installation.

  3. If you don’t have a key yet, click I don’t have a product key → install Windows → activate later.

4. Method 4: Buy a License from Microsoft Store

If you don’t have a key or license:

  1. Go to Settings → System → Activation.

  2. Click Go to Store.

  3. Purchase a Windows 11 Home or Pro license.

  4. It will automatically activate with your Microsoft account.

5. Method 5: Troubleshoot Activation Issues

If Windows 11 doesn’t activate:

🔹 Check Internet Connection – activation requires online verification.

  1. Go to Settings → System → Activation.

  2. Click Troubleshoot.

  3. Follow on-screen instructions.
