Microsoft releases Windows 10 build 20152 to the Dev channel

It's Wednesday, and that means that it's time for a new Windows 10 Insider Preview build in the Dev channel. This week, it's build 20152. Unlike last week, there are no new features in the build.

It's from the Iron development branch, but according to Microsoft, the builds in the Dev channel aren't tied to a single release. This only happens when it gets promoted to the Beta channel.

As for build 20152, there are only a bunch of fixes and some known issues to be aware of. Here's what got fixed:

  • We fixed an issue that could result in Notepad unexpectedly being removed after resetting your PC. If you were impacted by this, you can reinstall Notepad via Optional Features in Settings.
  • We fixed an issue where the “Windows needs space to continue” dialog might have told you to select Continue but no Continue button was displayed.
  • We fixed an issue that could result in the Windows Update icon unexpectedly not appearing in the notification area of the taskbar when an update was ready for reboot.
  • We fixed an issue that could result in an IME typing as if it was ON, when it was actually in OFF state, and tapping the IME mode indicator in the taskbar wouldn’t change the mode.

Here are the known issues:

  • We’re working on a fix for an issue causing some systems to crash with a HYPERVISOR_ERROR bugcheck.
  • We’re looking into reports of the update process hanging for extended periods of time when attempting to install a new build.
  • We’re aware of an issue where Notepad might fail to reopen files which were automatically saved during a PC restart (if that option is enabled in Settings). Documents can be recovered from %localappdata%\Notepad.
  • Some Insiders may experience a bugcheck and rollback when attempting to update to this build if an Xbox controller is connected to your device. You may see error code 0xc1900101 in Windows Update History. To work around the issue, disconnect or unpair the Xbox controller to successfully update. (Please note that reconnecting the controller after the update will result in a bugcheck.)
  • Starting with the last build, some games and applications may crash at launch or fail to install. We’ve identified the root cause and are working on a fix for a future flight.
  • We’re investigating reports of the screen becoming dimmer after upgrading to the previous build.
  • We’re aware of an issue where Task Manager reports 0.00 GHz CPU usage in the Performance tab.
  • We’re working on a fix for an issue causing Reset this PC to always show the error “There was a problem resetting this PC” when launched from Settings. To work around the issue, use Advanced Startup (Windows RE) to start Reset this PC.

As usual, you can get today's build via Windows Update. If you're not on the Dev channel just yet, you can get started through the Windows Insider Program tab in Settings, although the Dev channel might still be called the Fast ring.
