Microsoft update the Windows 10X Emulator image to build 19578

If you are testing Windows 10X there is a new image and an update to the emulator available. Microsoft have updated the Microsoft Emulator and the Windows 10X emulator image taking the build number to 19578. The new build includes updates to the Win32 Container which should improve compatibility with Win32 apps. The windowing experience of Win32 apps been updated for a more consistent placement of app windows.

The Windows 10X Emulator Image (build 19578) includes a new EULA that no longer requires it to be installed on an Insider Preview version of Windows. You can install it on Windows 10 version 10.0.17763.0 or higher to test existing apps on the dual-screen device emulator.

In order to use an Insider Preview SDK, developers must setup their dev environment on a Insider Preview version of Windows.

This update applies the windowing model for Windows 10X to your Win32 apps running in the container. System-defined window placement ensures that users have a consistent and simplified windowing experience that is tailored and appropriate to a smaller, dual-screen, and touch-friendly device. Some gaps remain and will be addressed in a future update.

An early version of File Manager (labeled Beta) is included. It is designed to work with OneDrive synced files and therefore requires a Microsoft account attached to the OS, either through the Settings app or by signing into a Microsoft app such as the Store.

Installing the Visual Studio Remote Tools no longer prompts about the Machine.config files during install.

Emulator displays “The GPU is not running. Problem code: 43”. There is a recent regression that fails to initialize the GPU if the host machine is an older build than the Windows 10X image.

The LockScreen may stop responding. If it does, use the device portal and restart the ModernShellUXApp.exe process.

Occasionally, apps running in the Win32 Container may not display correctly. Tapping the tile in the taskbar typically brings up the app properly.

The Emulator adds in the ability to download images from the store so you don’t have to download the manually. Also you no longer have to run the installer on a Windows Insider joined PC, you can install it on a PC running Windows 10 version 17763 of higher.
