The OPS-M (Windows version) comes pre-loaded with Windows 10 IoT Enterprise 2016 LTSB. This version of Windows 10 is part of the Long Term Service Branch, and will receive security and stability updates from Microsoft for ten years.

It is designed for maximum stability, so updates will not be installed automatically; they must be initiated by the administrator. This operating system will allow the user to install applications and software packages like MS Office, but they must be installed directly because the Microsoft store is not supported.
