Run command as admin : “slmgr /dlv” To display current license information.

If “Error: Product key not found” is displayed – reload KMS key for specific product from technet

“slmgr /ipk xxxx-xxxx-xxxx-xxxx-xxxx”
“slmgr /dlv” should now show product license information but say un-activated

Run “slmgr /ato” – you should get a message saying successfully activated.

Running “slmgr /dlv” – should show you the activation information and also say “activated” as confirmation.
