Hi Sam. I'm Greg, an installation specialist and 8 year Windows MVP, here to help you.
Any retail version of Windows, once it is activated, will remain activated without needing to check in with Activation servers.
Only Volume License keys used by businesses and organizations need to periodically check in with their home servers to have activation renewed.
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
