As expected, Microsoft has released a new build to PC and Mobile Insiders today. Windows 10 Beta 14388 brings 44 new fixes, with a focus on reliability and battery life improvements. Since the release of Windows 10 Insider Preview 14385 on Saturday, we have seen several reports of installation failures, driver crashes, and other problems. It is unknown if any of these problems have been fixed in the latest build or not. We will be keeping our readers updated with the latest improvement and bug fixes.

Windows 10 beta 14388 brings some known issues for PC, including a fix that will "affect the ability to boot Windows Server 2016 Tech Preview 5 VMs with Secure Boot enabled."
