What’s new in Build 18312
Reserving disk space to keep Windows 10 up to date
Through reserved storage, some disk space will be set aside to be used by updates, apps, temporary files, and system caches. Our goal is to improve the day-to-day function of your PC by ensuring critical OS functions always have access to disk space. With reserved storage, updates, apps, temporary files, and caches are less likely to take away from valuable free space and should continue to operate as expected. Reserved storage will be introduced automatically on PCs that come with 19H1 pre-installed or on PCs where 19H1 was clean installed.
Reset this PC UI Improvements
We added new UI for Reset this PC as part of Settings > Update & Security > Recovery. The new UI provides a more consistent experience across devices with different configurations and requires fewer clicks to complete.
Windows Subsystem for Linux Command Line Tool Improvements
We added new command line options to the WSL command line tool (wsl.exe) for easier WSL management and added functionality based on your feedback. Below is a summary of changes.
For members of the Fast Ring in the Windows Insider project, Microsoft today released the Windows 10 Insider Preview Build 18312. This version update is not large, mainly introduced the Reserved Storage settings, and improved the Reset this PC interface.
