Windows 10 build 17133.1004 for HoloLens rolling out for Insiders

Last week, Microsoft rolled out the first preview build of Redstone 4 for the HoloLens, which hadn't received any major new version of Windows 10 since the Anniversary Update. That initial RS4 build can only be installed if you flash your HoloLens with an FFU that Microsoft has provided, which would bring you up to build 17123. Today, Microsoft is rolling out the RS4 RTM build 17133 to Insiders running HoloLens RS4.

Unlike build 17123, which required flashing an FFU onto a HoloLens to get it, build 17133 is rolling out like a normal update via Windows Update, meaning those on RS4 can grab it and install it without having to wipe their HoloLens first. Build 17133 is only available for those already running build 17123, so if you're still on build 14393, you'll need to flash the 17123 FFU onto your HoloLens first before you can acquire the RS4 RTM.

Changelog for this build{.nofollow} is pretty short, likely because build 17123 is the one that brought all the new features. 17133 is more of a bug fix and last minute clean-up build.

  • Fixes for speech reliability and overall reliability of the product.
  • Known issue: Users may experience reliability issues with using voice to place Skype calls or launch apps for the first time.

  • I have a feeling that microsoft would be announcing that it would be cancelling this product
  • You mean going back to the sticks and stones? Not happening.
  • Based on what?
  • When will it become commercial
  • Till we have enough software from business partners. Legacy software don't go well with new toys. Or, you can buy one and start coding.
  • I just can't get passed my mixed feelings including sorrow, joy, pity when reading these lines:
    "- Fixes for speech reliability and overall reliability of the product.
    - Known issue: Users may experience reliability issues with using voice to place Skype calls or launch apps for the first time."
    So after all, what was fixed then?
  • read the changelog for 17123 it's a pretty massive leap from the anniversary update
  • For sure. Still it would not change my thoughts on build 17133 and these lines.
  • Hololens is still a thing? How many years does a product need to be in development/beta?
  • Till we have enough software from business partners. Legacy software don't go well with new toys. Or, you can buy one and start coding.
  • Updating now. The first RS4 build made the UI more fluid but speech recognition worked poorly if at all so this fix is welcomed. The store also lags terribly, but that may be the store app itself. No other apps seem to slow down. I like the autoplacement of windows and two handed gestures. What's most encouraging is the rapid update. After 19 months of silence, things are finally picking up. Good to see evidence with the new build.
