Quote:Microsoft has released a new Windows 10 19H1 preview build for Fast ring insiders, and the changelog includes several refinements for Windows Sandbox.

Windows 10 build 18353 is one of the last builds that are shipped for the 19H1 development branch, as Microsoft is projected to finalize this feature update in late March.

However, it brings several major improvements, including for Windows Sandbox, which is a key feature of the upcoming release.

First and foremost, Microsoft says that Windows Sandbox now comes with microphone support, and this means that accessibility will thus be possible as well.
Additionally, users can now configure the audio input devices via the Windows Sandbox config file.

Beginning with this update, Windows Sandbox also comes with fewer bugs, as Microsoft has fixed an issue causing this virtual environment’s time zone not to be synced with the host.
