Preview Build Highlights
Reserving disk space to keep Windows 10 up to date.
To ensure critical OS functions always have access to disk space, some disk space will be set aside to be used by updates, apps, temporary files, and system caches. (Build 18312)
FLS Slot Limit Increase.
This build greatly raises the per-process Fiber Local Storage (FLS) slot allocation ceiling, allowing the loading of potentially thousands of unique DLLs that have statically-linked Visual C++ runtimes, or otherwise allocate FLS slots. (Build 18312)
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. (Build 18312)
Streamlined Windows Hello PIN reset experience.
We know remembering a PIN can be tricky for users, so we have revamped the PIN reset experience with the same look and feel as signing in on the web. (Build 18309)
Run untrusted software with greater confidence.
With Windows Sandbox, you get a lightweight desktop environment for safely running applications in isolation. (Build 18305)
More detailed Protection History.
The Protection History experience has been updated to give more detailed and easier to understand information about threats and available actions. (Build 18305)
Introducing Tamper Protection.
This new setting from Windows Defender Antivirus, available in the Windows Security app, provides additional protections against changes to key security features. (Build 18305)
Automatic Restart and Sign On (ARSO) for Enterprises.
This feature automatically signs in a user after an update to finish set up and then locks the PC. As part of our Seamless Update Story for Windows, its goal is to reduce customer pain points around updates. (Build 18305)
