If you downloaded from the official Microsoft website, you may encounter issues when activating using these installers.

The problem arises because Microsoft's website hosts "Evaluation" versions of Corporate operating systems. If you installed such a version, your system properties will show "Evaluation" in the version description.

The Evaluation version of Windows 10 cannot be activated with product keys and only works for 90 days. Afterward, the desktop background will turn black, and the system will restart every 90 minutes. When activating the Evaluation version, you will encounter the following error.

The solution to this issue is to reinstall the system with a full version. You can download the necessary version of "Windows 10 Enterprise" from our catalog. Additionally, you can purchase a product key from our online store.
We have product keys available for various versions of Windows 10 Enterprise:
