Microsoft Delivers Cumulative Update to Windows 10 Mobile Insider Preview

Microsoft today released a cumulative update for the Windows 10 Mobile Insider Preview, bumping the build number in the process to 10586.71. Despite the long wait between releases, there are no new features, just fixes.

“This Cumulative Update contains additional bug fixes,” Microsoft explains. “Windows Insiders in the Fast ring will also notice an Insider Fast Configuration Update that will update an expiring certificate to ensure your device will continue to receive future [builds and updates].”

Here’s what’s fixed in this update, which is available to Fast ring testers only:

  • Windows Update gets performance and reliability improvements.
  • Better upgrades from Windows Phone 8.1. Microsoft made improvements in the migration of data profiles and messaging settings for those upgrading from Windows Phone 8.1.
  • SensorCore APIs are now upgraded correctly from Windows Phone 8.1. Now, applications, including many fitness applications, can once again correctly access movement data.
  • Improved SD card detection. SD card detection has been improved on boot and after insertion, and File Explorer now handles the removal of an SD card when the default for apps or photos are set to SD.
  • Edge improvements. The Edge browser picks up PDF rendering and other improvements.
  • Bluetooth improvements when re-connecting to already-paired devices and cars, turn by turn directions, and when using Cortana with Microsoft Band.
  • Settings improvements. Download maps and changing Quick Settings have been improved (somehow).
  • Groove improvements. If you reinstal Groove Music from the Windows Store, you will no longer see DRM music playback issues. And Groove Music local song collections are now imported more quickly.
  • Device power improvements. No specifics again, but there are device power improvements “after listening to music, after missed phone calls when iris detection is disabled, and when downloading updates.”
  • In app purchases improvements. In app purchases now work correctly when cellular data is disabled.
  • Kid’s Corner improvements. Kids Corner is now more reliable.

Looking ahead, Microsoft says it has been working on addressing Windows Insider feedback about the update experience, which still requires full blown build-over-build installs for even minor updates like this, and can be very time consuming and unreliable.

“Windows Insiders that downloaded the Configuration Update that was published on Friday, or has a device that was automatically updated over the weekend, will experience improvements in the performance and reliability of receiving this Cumulative Update,” the firm notes. “But if you have not yet downloaded the Configuration Update to your device, it will be included in the download with this update.”
