A new device, Fujitsu Lifebook P727, will be available also, but with Windows 10 S installed by default. More specifically, the main goal is to complete the Fall Creators Update with the new Windows 10 Inside Preview 16278. Windows 10 was designed as a service, whereby feature updates are required a couple times a year.
You can save all of your creations in OneDrive Files On-Demand, accessing your cloud files like any of your other files on your PC, without using up your local storage space.
The Photos app will also be able to deliver what Microsoft calls "remixed experiences". Starting at $350, the Lenovo Explorer fits the bill nicely with its widespread functionality: users can watch 4K TV shows, view 360-degree video, play VR games, and even use the headset for productivity via Windows programs like Excel. When bundled with motion controller, the headset will cost $449.
If you are using Windows 10 1511 within an organization, Microsoft terminated support at the end of July, so you should be on a supported release such as 1607 or 1703.
The Windows 10 Fall Creators update arrives on October 17. That said, none of that is likely up to Lenovo as it's not actually creating the content, so any of the content that you do wish to experience should be found in the Windows store and will probably be compatible with any of the Mixed Reality headsets that are running on Microsoft's platform. Windows Defender Antivirus will also begin pulling information from analysis of the billions of data points available via Microsoft's Intelligent Security Graph, to better identify threats and improve protection.
