We've got another Insider Preview build to dig our hands into! This time, build 16241 for PC and 15230 for Mobile is rolling out to Insiders in the Fast ring!

Microsoft is now rolling out another Insider Preview build for Insiders in Fast ring on PC today. This weeks build is 16241 and is backing more bug fixes, enhancements and changes for Insiders to get testing. Also this week, we're getting build 15230 for Mobile!

What's new for PC?

Windows Shell Improvements

  • Recover your pin and password from the lock screen:  Self Service solutions empower end users, unburden helpdesk/IT admins, and save organizations money. Cloud Self Service Password Reset (Cloud SSPR) has been a really popular Azure AD Premium (AADP) feature and now we want to take this great capability one step further – Windows Integration. If you're using an AADP or MSA account and you find yourself stuck at the login screen, you can now reset your password and PIN straight from here.
  • Refining Acrylic Material: We've heard your feedback, and in response in today's build you'll notice we've softened the noise layer of Acrylic Material.

PC Gaming Improvements

  • We fixed an issue preventing profile cards in the Xbox Live in-game experience from working.
  • We also fixed an issue causing Game bar to crash while broadcasting.

Task Manager Improvements

  • The GPU name is now shown on the left-hand side of the Performance tab for each GPU.
  • We now default to the multi-engine view, which shows performance monitors for the four most active GPU engines. Typically you'll see charts for the 3D, Copy, Video Encode and Video Decode engines. Right-click on the chart to switch back to the single-engine view.
  • There is now a total GPU memory text counter next to the dedicated and shared text counters at the bottom of the Performance tab.
  • The Direct X version now also contains the highest supported DX feature level.
  • Starting in Build 16241, additional processes (such as the Chakra JIT Compiler, UI Service, and Manager process) are now labeled in Task Manager. We'll continue to revise these labels based on feedback.

Mixed Reality Improvements

  • Added support for Mixed Reality Motion Controllers over USB (Wireless/Bluetooth support to come soon!)
  • Connection reliability improvements (Code 43 errors in Device Manager).
  • We've updated the Mixed Reality Portal icon.
  • We've updated teleportation experience to make this more intuitive and direct.
  • We have also improved stability of the headset during your Mixed Reality session.
  • We have fixed the issue where the Hill on the side of the cliff house flickers.
  • We have also fixed where the audio of HoloTour can now turn off promptly when switching between apps and cliff house.
  • we have also fixed speech commands to work during exclusive app sessions.
  • We have also improved the experience where we can now load the Environment effectively with no black screen during startup.
  • Mixed Reality Portal now explicitly informs users that headsets require USB 3.0.
  • Improved support for ASMedia and other 3rd party USB controllers
  • 4K 360 Video streaming has also been improved in this build.
  • 3Glasses improvements: we have fixed various issues with 3Glasses headset and controller to help jumpstart your development.
  • Preset holograms in the Cliff House now show up in the right order.
  • We have also fixed the issue where black screen is shown when the environment is loading.
  • We have fixed the headset's sleep cycle to correct according to user activities.
  • We have also fixed the issue to enable users to share the Mixed Reality captures to Facebook.

Delivery Optimization Improvements

  • Delivery Optimization has been synonymous with "Peer-to-peer" but few people are aware that it is also used as the main downloader for content downloaded from Windows Update and Windows Store. Delivery Optimization, even without P2P, is what makes downloads from Windows Store much faster as well as makes downloads of Quality and Feature updates far more reliable. In line with this, the main settings page – now titled "Delivery Optimization" – indicates that while you can enable or disable the P2P functionality, Delivery Optimization is still used when downloading updates and apps directly from Microsoft's content servers.
  • Activity Monitor: Here you can see the overall bandwidth used in downloads of OS Updates including Feature and Quality updates as well as Store App downloads and updates on your device. You will also be able to see exactly the amount of data coming from other PCs on your local network or other PC on the Internet based on your settings.

What's new for Mobile?

  • We fixed an issue where VPN profile appeared to be always ON.
  • We fixed a notification issue between the Bluetooth Support Service and device background services for fitness bands.
  • We fixed issues with Caller ID matching in Japan & Denmark.
