KMSAuto is the famous activator (loader) for windows which is well known because of its high-quality features, simplicity and secure activation. It is wise enough to select it for Microsoft products and you won't regret it.
I downloaded games on steam and KMSAuto Net 2015 v1.3.8 Portable to crack microsoft office but it contains windows activator too so i deleted it, not sure if i deleted it completely that's why i have the message of windows licence expiration. When i go to settings, it shows that windows is activated using your organization's service.
Agree with Sharath Reddy. You are using the old version of the activator. More addition according to my knowledge you are not blocking host in your windows. Try this tutorial how to block host in windows and then you need to install .Net Framework you can grab from the official Microsoft website. Now you need to download the the latest version KMSAuto Net 1.5.4 Portable Download. Make Sure you have done all the above 2 steps then run activator now.
Ping Me if you still have an issue i will assist your further.
