If you don't wish to receive feature updates like the one with big version changes I only have a single hint for you: Windows 10 Enterprise 2016 LTSB. It is a Windows 10 version with extended support and therefore it only receives security updates and no big major upgrades. In addition to that it doesn't have all the Microsoft Store apps, it doesn't have Cortana and etc. Telemetry can be disabled and updates can be controlled via GPOs.

The ISO is freely available online. Here is a free high speed mirror of the official MSDN ISOs of Windows 10 Enterprise 2016 LTSB.
