Windows 10 RS5 Build 17686 for HoloLens Released

Microsoft today released a new update to its VR platform, Hololens. This is the first Redstone 5 preview build of Windows 10 Redstone 5 for HoloLens. If you own compatible hardware, you can install it now.

Hololens Rs4preview 2

This build is delivered over the air (OTA) through Windows Update after you've manually installed the HoloLens RS4 Preview using the instructions here.


The changes in this release are minor and include mostly bug fixes.

Microsoft expects that mixed reality will change the way we work in the near future. They expect Firstline Workers and Information Workers to benefit significantly from solutions that blend their physical and digital reality.

Microsoft is trying to attract even more developers by supporting more tools and technologies on its platforms with the HoloJS framework. HoloJS is a C++ library that hosts Chakra (Microsoft's own JS rendering engine used in Edge) to run JavaScript code, and also hosts ANGLE to handle OpenGL ES graphics calls. OpenGL ES calls are translated from WebGL calls by the JavaScript app. When running on Microsoft HoloLens, HoloJS supports holographic rendering. There are also some useful samples of HoloJS apps already available so if you'd like to check out what Microsoft's new apps framework for HoloLens has to offer, you should definitely check out the official GitHub repository for it.

Windows 10 April 2018 Update for HoloLens will be released on June 26. Starting June 26, users will be able to download and install it using Windows Update just like on a regular Windows 10 PC. For the end user, the update will bring the following changes and features:

  • Auto-placement of 2D and 3D content on launch
  • Fluid app manipulation
  • 2D app horizontal resize with reflow
  • Expanded voice command support
  • Updated Holograms and Photos apps
  • Improved mixed reality capture
  • Improved audio immersion
  • File Explorer
  • MTP (Media Transfer Protocol) support
  • Captive portal network support during setup

And more.

  1. This is offtopic but I’m starting to experience issues to this site because of a certificate problem. Can you look at it? Chrome is saying that my connection is not private.

  2. I know you can. However, companies like Google are making it harder with even tougher security because of global attacks and vulnerabilities like WannaCry and Spectre.
    About this article, I would really love Microsoft to be able to release the Hololens to the general public. I’ve tested the emulator and it’s already looking promising.
