Changes and improvements​

[Live Captions]​

  • We're improving Live Captions with a new Include Screen Reader audio setting, which is off by default. With the setting off, Live Captions won't transcribe audio from screen readers such as Narrator, JAWS, and NVDA, keeping captions focused on microphone and system audio.

    Enable or Disable Include Screen Reader Audio in Live Captions on Windows 11

    This tutorial will show you how to turn on or off including screen reader audio with Live Captions for your account in Windows 11. Live captions helps everyone, including people who are deaf or hard-of-hearing, better understand audio by providing automatic transcription. Captions are...

[Hyper-V]​

  • 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.

[Other]​

  • Fixed an issue where backing up using File History unexpectedly failed with an error saying, "No usable drives found."

Reminders for Windows Insiders in the Beta Channel​

  • Updates are based on Windows 11, version 25H2 via an enablement package (Build 26220.9492).
  • 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.

It doesn't appear Microsoft gives a checksum to compare the SHA256 with at the Insider download site.

I am downloading from the link posted by brink yesterday. UUP dump.
I have wrong system date 18-September-2026.
Today is 19-September-2026.
Hope this do not corrupt windows 11 26H2 insider preview 26340.4905.
Where can the hash number of this yet to be complete iso be.
So that chances of iso corruption during installation is very less.
