The optional October 2026 preview moves 25H2 and 26H2 to builds 26200.9818 and 26300.9818 and may add one Secure Boot restart.

Microsoft released optional preview cumulative update KB5127936 for Windows 11 versions 25H2 and 26H2. It includes 41 feature and quality changes, including a faster File Explorer context menu, Cloud rebuild without USB media, and WinRE reuse of saved Wi-Fi profiles, but no security patches. Installed devices move to builds 26200.9818 and 26300.9818. Microsoft said some devices may restart once more as replacement Secure Boot certificates roll out before the 2011 certificates expire in late June 2027.

Key facts
  • Preview updates are optional and do not include security patches.
  • Cloud rebuild can reinstall Windows using an image from Windows Update.
  • WinRE Wi-Fi reuse is on by default and IT admins can disable it.
  • Hibernation is reduced above 80% battery and starts earlier below 10%.
