Microsoft rolled out a new build of Windows 10 to Insiders in the Beta and Release Preview Channels yesterday. The update brings PCs to build 19042.804. The build doesn't include any new features but does include several bug and security fixes.

Here are the key changes, as outlined in a blog post from Microsoft:

  • We fixed a possible elevation of privilege vulnerability in the win32k component.
  • We fixed an issue that might damage the file system of some devices and prevent them from starting up after running chkdsk /f.
  • We fixed a security vulnerability by preventing applications that run as a SYSTEM account from printing to "FILE:" ports. To address this issue in the future, make sure your applications or services run as a specific user or service account.
  • Security updates to the Windows App Platform and Frameworks, Windows Apps, Windows Input and Composition, Windows Cloud Infrastructure, Windows Management, Windows Authentication, Windows Fundamentals, Windows Cryptography, Windows Virtualization, Windows Core Networking, and Windows Hybrid Cloud Networking.

You can read more about the build, including known issues and workarounds, on a Microsoft support page.
