Announcing new builds for 18 September 2026

Read on windows.com

Summary

Microsoft released new Windows 11 Insider Preview builds for Beta and Experimental channels, adding a sleeker mouse indicator animation, a contrast theme toggle in Magnifier, and enhancements to Cloud rebuild that allow drive sanitization and remote triggering via CSP. These changes affect accessibility users, IT admins, and anyone testing the latest builds.

  • Mouse indicator gets a new animation and can stay on until Escape is pressed, configurable in Accessibility settings.
  • Magnifier adds a contrast theme toggle to reduce screen glare without full color inversion.
  • Cloud rebuild now can sanitize drives during a reinstall and can be started remotely via the Recovery CSP.
  • New Insider Preview builds are available: Beta 26220.9492, Experimental 26340.9502, plus Experimental 26H1 and Future Platforms builds.

IT administrators and accessibility users should note the remote Cloud rebuild capability and new UI accessibility tweaks.
