Before you start

Make sure Windows 11 is installed and you are connected to the internet. Have your 25-character product key ready — you will find it in your Software Keys HQ order email.

Step by step

Open Settings, then System, then Activation.
Click "Change product key" next to the activation section.
Enter your 25-character key and click Next.
Wait a few seconds while Windows verifies the key with Microsoft.
When you see "Windows is activated", you are done.

Troubleshooting

If activation fails, wait a few minutes and try again — keys sometimes need a moment to register on Microsoft's side. Check your internet connection and that your system clock is correct. If it still fails, contact support with your order number and we will sort it out fast.
