Windows 10 build 20152.1000

Windows 10 build 20152.1000 is the second Insider Preview build of Iron. This build was released to Windows Insiders in the Dev Channel on 24 June 2020.

History

 * Two days prior to the public release of this build, a comment was made by a Microsoft employee on GitHub regarding an issue with the WinUI 2  XAML template when the High Contrast White theme was enabled.
 * The details of the issue were:


 * The  template didn't display until the user hovered over it, while on the regular version, the scroll indicator was always visible.
 * The  template's handle was always white.

Bugs

 * There's a chance that the system may crash with a  BSOD.
 * The update process to this build has a chance of hanging for extended periods of time.
 * Notepad may fail to open files which were automatically saved during a PC upgrade (or restart if enabled in Settings). Saved documents can be recovered from.
 * At the time of this build's release, there was a chance of the system crashing with a BSOD during the update process if an Xbox controller was connected to the device, and it would consequently roll back to the previous build as a result. After the rollback, the error code 0xc1900101 would appear on the Windows Update history page. A workaround was to disconnect or unpair the Xbox controller to successfully update to this build.
 * Some third-party games and applications may crash at launch or fail to install on this build.
 * Sometimes the screen can randomly become dimmer after upgrading from a previous build.
 * Task Manager has a chance of showing a CPU speed of 0.00 GHz on the Performance tab. It may also sometimes show abnormally high values.
 * Reset this PC does not work if launched from the Settings app, giving you the error "There was a problem resetting this PC." To workaround this issue, start the tool from Windows Recovery Environment.
