Microsoft has recently signed an agreement with the United States Department of Defense to install Windows 10 on all its 4 million computers, but it turns out that the partnership is going much better than anyone ever imagined.

In a recent interview with Fedscoop, Pentagon's CIO Terry Halvorsen praised Windows 10’s security and recommended employees of the Department of Defense to install Microsoft’s latest operating system on their home computers too.

“If you're using a computer at home and you're not on Windows 10, you're doing yourself an injustice - you ought to be moving to Windows 10,” he said in the interview.

“We're going to put out some guidance to our employees in general - it's not an endorsement of Windows 10 or Microsoft specifically - listing what the characteristics of Windows 10 would give you if you put it in your home system. That's as close to an endorsement as I can get for a software product.”

Windows 10 on as many devices as possible

It goes without saying that such statements help Microsoft bring Windows 10 on as many devices as possible, especially because the software giant’s struggling to convince more people to upgrade.

Windows 10 is currently offered as a free upgrade to those running Windows 7 or 8.1 on their PCs, with the promo to end on July 29 this year. The goal here is to bring Windows 10 on 1 billion devices by 2017, a milestone that Microsoft expects not only thanks to the free upgrades, but also thanks to enterprises and organizations in the education sector that join the Windows 10 bandwagon.

The deal the company has with the US Department of Defense and which will bring Windows 10 on 4 million devices is living proof that striking deals with authorities in the US and overseas is a huge win for Microsoft, especially when they’re followed by such statements that encourage employees to make the move to the new operating system too.
