In compliance with a Deputy Secretary of Defense mandate, the Army is moving systems and equipment running the Microsoft Windows operating system to version 10. This enterprise-wide upgrade will be applied to all existing Windows clients on DoD information networks and all unclassified, Secret and Top Secret collateral information systems, to include: desktops, laptops and tablets; Special Access Program systems; mission systems; strategic, tactical, research and development, and training and evaluation systems; platform information technology; and weapon systems (to the maximum extent practicable). It does not include Windows cell phones or Microsoft Server operating systems.
DoD is transitioning to Windows 10 to improve the department's cybersecurity posture, lower the cost of IT and streamline the IT operating environment. Under Windows 10 and the Secure Host Baseline, patching and security updates will occur more quickly and the Army will be better able to counter certain common cyber-intrusion techniques. Additionally, greater accountability and transparency across the department's networks will allow cyber defenders to better detect malicious activity. Establishing a DoD-wide common operating system also will promote faster and easier implementation of technology upgrades, and enable DoD to leverage common applications and enterprise solutions. That, in turn, ultimately will lower information technology-related costs.
The Army is approaching Windows 10 migration methodically and in collaboration with the overall DoD lead, U.S. Cyber Command. The CIO/G-6 and its Army partners are developing governance, command and control processes, and other necessary guidance and directives to aid and enforce compliance with the transition to Windows 10. CIO/G-6 will keep Army organizations apprised of the implementation timeline and associated actions the field must take to accomplish the transition.
