Personal Computer (PC) Operating System Standard

April 7, 2015


This standard establishes the minimum expected operating system requirements for personal/client computers (non-Server computers) purchased and used by state agencies.


PC/Client computing devices comprise the largest set of individual computing devices employed by the State IT Enterprise. PC/Client computers support numerous information technology and automation tasks, both independently and in conjunction with Server-class computing devices. Creating and adopting an operating system standard supports security, procurement, and operational computing objectives that protect State data, promote technology integration, streamline asset purchasing, and optimize support models and standards.


This standard sets the minimum requirements for PC/Client operating systems, procured through normal processes and channels, intended for use in State government. This standard applies to all agencies as defined by Iowa Code Chapter 8A, Section 101. Non-participating agencies are encouraged to follow the guidelines in this and other enterprise security standards.


  • PC/Client Computing Devices: Desktop, Laptop, and Workstation-class computers that are capable of running an operating system that allows both non-networked computing task capabilities, as well as network-based, client-server computing task capability.


This standard will be reviewed at least every two years and updated as needed.
