Microsoft HoloLens 2 is an untethered holographic computer. It refines the holographic computing journey started by HoloLens (1st gen) to provide a more comfortable and immersive experience paired with more options for collaborating in mixed reality. HoloLens 2 runs on the Windows Holographic OS, which is based on a "flavor" of Windows 10, that provides users, admins, and developers with a robust, performant, and secure platform.
Note : The recent Windows 11 announcement was focused on the PC version of Windows. We recently launched a major OS update to HoloLens 2 in May 2021, and we are working on an upcoming release based on customer feedback for this fall.
A user account is required to use [HoloLens 2].
