The latest Windows 10 Insider Preview is build 10130, which Microsoft released a few weeks ago, and which it has since patched with further interim updates. Yesterday, a new build of the Windows 10 Insider Preview leaked onto the web.
As we revealed in our screenshot gallery, build 10147 introduces updated UI elements, Edge branding and a dark theme for the new browser, and colored title bars, along with the new Phone Companion app, additional wallpapers and Cortana improvements.
Now, the release notes for build 10147 have also been leaked by WZor, revealing some of the bug fixes and known issues in this latest version.
Among the various fixes that have been applied are a new third party Wi-Fi driver and chipset; a fix that prevented video playback controls from appearing on some sites in Microsoft Edge; and the ability to downgrade back to an earlier Windows 7, 8, or 8.1 installation.
While build 10147 comes with various known issues, none of them are new to this build specifically, which suggests that Microsoft is succeeding in its efforts to squash bugs and add more polish to Windows 10 ahead of its launch next month.
One issue that's particularly worth highlighting is the last one on the list. "If you play a media (video or audio) clip or stream," it says, "OneDrive wakes up the CPU every ten milliseconds just to wait on an event. This behavior causes a significant battery drain and battery telemetry problem."
That's certainly something to bear in mind if you've installed build 10147 on a notebook or tablet. You can check out the rest of the release notes in the gallery or via the source link below.
