Fixes and known issues


  • IMPORTANT NOTE FOR DEV DRIVE USERS: Insiders on Build 26068 and higher who have Dev Drives should no longer see their Dev Drives breaking when rolling back as long as you roll back to Build 26063 and higher. Rolling back to earlier builds may still result in issues with Dev Drives.
  • IMPORTANT NOTE: Fixed an issue causing Windows Update in Settings to not load or crash in Build 26063. If you are still on Build 26063 and encounter this, rebooting may resolve the issue. If it doesn’t, the update should still eventually download on its own – appreciate your patience.
  • Fixed an issue for Narrator not working when setting up a device or in Advanced Startup.

[Copilot in Windows*]

  • Fixed an issue where if you turned the Copilot icon off and back on in Settings never showed it on your taskbar again.
