- Fixed an issue where some applications that used HCS-managed virtual machines experienced issues when sharing host folders with Linux VMs using Plan9. Folders shared from the Windows host using Plan9 didn't appear or couldn't be accessed in the guest environment.
Reminders for Windows Insiders in the Beta (26H1) channel
- The desktop watermark shown at the lower right corner of the desktop is normal for Windows Insider pre-release builds.
- Features and experiences included in these builds might never get released as we try out different concepts and get feedback. Features might change over time, be removed, or replaced and never get released beyond Windows Insiders. Some of these features and experiences could show up in future Windows releases when they're ready.
- Some features in active development we preview with Windows Insiders might not be fully localized, and localization will happen over time as features are finalized. As you see issues with localization in your language, report those issues to us via Feedback Hub.
- Check out Flight Hub for a complete look at what build is in which Insider channel.
