About HoloLens 2
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.
Important
We continue to support ARM32 and ARM64 on HoloLens 2.
A user account is required to use HoloLens 2.
