Windows 7: Activate license - how it works

After installation, you have 30 days to activate Windows 7. Otherwise you can no longer use the calculator. We show you different ways how you can unlock Windows quickly.

Within seconds: activate Windows 7 over the Internet

The easiest way to activate Windows 7 is via the Internet. To do this, proceed as follows:

1. Click the Windows button at the bottom left to open the Start menu.
2. In the right column you will find the entry "Computer". Right-click on it and select "Properties".
3. If Windows has recognized your Internet connection, you will find the button "Activate Windows online now" here. Click on it and then confirm the administrative warning message.
4. Now you have to enter your product key. You can find this either on the computer case or in the sleeve of the installation DVD. If you purchased Windows 7 online, the activation key is in the email in your email inbox.
5. Confirm your entry by clicking "Next" and follow the last instructions. Windows 7 is now successfully activated and should show the same message as in the screenshot.

Alternatively: activate Windows by phone

If Windows gets in the way when activating the Internet or you cannot establish a connection, there is another solution: Windows 7 can also be licensed by phone.

1. To do this, open the Start menu and right-click on the "Computer" entry. Select "Properties" from the context menu.
2. In the new window, click on "Show other activation methods" and enter your product key.
3. Then select "Use automatic telephone system" and confirm the administrative warning message here too.
4. In the dropdown list you should now choose the location that is closest to you. Then click Next".
5. Now dial one of the phone numbers listed. A computer voice guides you through the activation.
6. You will now see an installation ID on the monitor. Enter them on the phone when prompted.
7. You will then receive a confirmation ID that you can enter on your computer.
8. Windows is now successfully activated. If there are any problems here, just stay on the line. You will then be automatically connected to Microsoft customer service.

Here we explain how you can check the activation again later.
