Anyone run KMS Activation method need to buy KMS Host key from Microsoft. The only difference between KMS Host key owner is they have their own server to run activation.
It save to use manually KMS method here. Actually, all method here is safe to use, all update from MIcrosoft. I Have run firewall and virus program in my PC, never have report something steal from my PC.
But, remember, all KMS activation method is only work for 180 days, when you online afterwards , it will automation renew activation back to 180 days.
