Dear FALE59,
Thank you for reaching out regarding your Windows activation issue. I understand that activation through Visual Support was working earlier this week but is no longer functioning. This situation can occur if there are temporary service interruptions, changes in your network configuration, or if the activation channel requires revalidation.
I recommend first confirming that your system date, time, and Internet connection are correct. I also suggest running the command slmgr.vbs /ato from an elevated Command Prompt to attempt activation again. If the issue persists, please verify that your product key matches the edition of Windows installed. In some cases, contacting Microsoft Support directly may be necessary to validate the license and complete activation.
I appreciate your patience and collaboration. Please click "Accept the answer" to support me. Thank you very much.
Kind regards,
QQ.
