We’ve learned (via Inside Defense) the United States Department of Defense has finally made the upgrade to Microsoft’s latest operating system, Windows 10.

Following their missing of the January 2018 deadline, the DOD finally made the transition complete by their second deadline on March 31st – news confirmed by acting DOD CIO Essye Miller in National Harbor, MD.

“For the most part, with the exception of a couple [offices], we are there,” Miller said.

“We’ll spend sometime this morning with the deputy secretary just congratulating folks for their hard work. It’s been a long, long, long journey,” she said.

The global superpower’s military branch moved to adopt Windows 10 sooner rather than later (higher education, corporate, and government bodies tend to operate a few operating systems behind from a stability standpoint) due to recent cyber attacks – as well as expanding their prowess for future missions and technology.

As with any organization-wide upgrade, some older machines were sadly let go and the ones unable to be upgraded in time were quarantined and denied access to their networks.

“Windows 10 obviously postures us on a security operating environment and that’s what we want,” Miller noted.
