In June 2016, Microsoft announced it would open Windows Holographic to all devices starting in 2017. It was followed in December by the announcement of the minimum specs required for the feature to work with Windows 10 PCs.
This new feature and the respective set of Windows Holographic headsets from Microsoft's partners were also available for trial at CES 2017. Attendees were able to experiment with VR headsets from Dell, Lenovo, HP, Acer, and 3Glasses.
And as spotted by MSPoweruser in a video released at Channel 9 last week, Microsoft has confirmed it will distribute developer kits for Windows Holographic at this year's Game Developers Conference. The conference will happen in the first week of March, one month ahead of the release of the Windows 10 Creators Update, expected for early April.
