Answer 1

Hello,

Ensure that the correct KMS client setup key is installed on your system:

Open Command Prompt as Administrator:

Press Win + X and select Command Prompt (Admin) or Windows Terminal (Admin).

Run the following command to check the current product key:

cmd

slmgr /dlv

Look for the Product Key Channel and KMS Hostname in the output.

If the key is incorrect or missing, install the correct KMS client key:

cmd

slmgr /ipk <KMS_Client_Setup_Key>

Replace <KMS_Client_Setup_Key> with the appropriate key for Windows 10 Enterprise.

slmgr /ato

This error code is related to Activation Server or License issue.

Open Command Prompt as Administrator and type in:

slmgr /dlv

You may also run the Windows Activation Troubleshooter

Settings > Update & Security > Activation > "Troubleshoot"

If the above fails, then open Command Prompt as Administrator and run:

slmgr /ato
