Hi, It seems that you have network connectivity issue. Based on the current situation, you may change the product key, run “SLUI 4.exe” and follow the wizard to re-activate Windows by phone. If you use KMS Server, please read the Microsoft KB article 938450 VP Mishra provided for further troubleshooting information.
