All four military services and agencies across the Defense Department are in agreement with a tight timetable to move to Microsoft Windows 10, Pentagon CIO Terry Halvorsen told reporters Friday.

There had been reports that individual military branches doubted the feasibility of making the transition by Jan. 31, 2017, as ordered by Deputy Secretary Bob Work in February.

But Halvorsen said that's not the case.

"[Army CIO Robert] Ferrell and I are in 100 percent agreement, as are the leadership of the Army and the [DOD] secretary, that our role remains to get Windows 10 in a year," Halvorsen said. "Are there challenges with that goal? Absolutely. Will we make that goal? I think we’re going to come awfully close to making that goal."
