Microsoft published the Windows 10 Insider Preview Build 18353 in the Fast Ring on March 8, 2019. This is the version in the 19H1 development branch that we expect to receive in April 2019 as Windows 10 V1903.

The announcement and a description of the changes can be found in the Windows Blog. Not much has been changed. There are the following fixes and improvements – but no new features:
- We've enabled microphone in Windows Sandbox, which among other things will improve several accessibility scenarios.
- We've added functionality to configure the audio input device via the Windows Sandbox config file.
- We've fixed an issue in which the Windows Sandbox time zone was not synchronized with the host.
- We've enabled the Shift + Alt + PrintScreen key sequence in Windows Sandbox which activates the ease of access dialog for enabling high contrast mode.
- We've enabled the ctrl + alt + break key sequence in Windows Sandbox which allows entering/exiting fullscreen mode.
- We fixed a recent issue resulting in some Insiders experiencing bug checks upon lid close, monitor plug, or monitor unplug.
- We fixed an issue resulting in preferred region settings getting reset on upgrade in the last few flights.
- We fixed an issue resulting in the Chinese version of multiple games not working.
- We fixed an issue in memcpy that caused some drivers to hard-hang the system on load; this could manifest as a hang on upgrade, depending on the system.
In addition, Microsoft has screwed into Windows Gaming Technology. But the preview comes with a number of known bugs:
- Launching games that use anti-cheat software may trigger a bugcheck (GSOD).
- Creative X-Fi sound cards are not functioning properly. We are partnering with Creative to resolve this issue.
- We're continuing to investigate feedback in the night light space.
- Some Realtek SD card readers are not functioning properly. We are investigating the issue.
- We're investigating an issue preventing VMware from being able to install or update Windows Insider Preview builds. Hyper-V is a viable alternative if available to you.
