The authenticity of this copy of Windows has not yet been confirmed
The error is often displayed if you have not yet entered the product key or if it is already being used on another PC.
- Open the Control Panel and select the "System and Security" category.
- Under "System" you will find "Windows activation" at the bottom.
- Click here on "Change product key" or "Activate Windows".
- You can then enter the correct or new code.
- If that doesn't work, you can also contact Microsoft here.
Second solution: bypass Windows activation
- A license key for Windows can only be activated on one computer. If you have Windows installed on two devices or with the same DVD, this can lead to problems.
- If you cannot or do not want to accept the help from Microsoft, you still have to bypass Windows activation. This is also possible if you have lost the key.
