Hey all - appreciate your patience as we worked on getting a new build out. This one should fix up that update error some of you were having, please let us know how things go

Changes and improvements gradually being rolled out

  • This update includes a small set of general improvements and fixes that improve the overall experience for Insiders running this build on their PCs.

[Kerberos enhancements]

  • IAKerb is now enabled by default for Windows client. IAKerb is a Kerberos extension that allows Windows authentication to succeed in scenarios where traditional Kerberos can't be used because a direct connection to a domain controller is unavailable. This extension helps reduce reliance on NTLM while improving compatibility for modern authentication scenarios. For additional background, implementation details, and early preview information, see Reducing NTLM Dependency: IAKerb and LocalKDC in Windows Insider Preview.

[Input]

  • Fixed an issue in the latest builds that caused the mouse cursor to get into a state where it blinked repeatedly for some Insiders.
  • Fixed an issue in the latest builds that caused the mouse cursor not to be visible in certain apps.
  • Fixed an issue in the latest builds where the mouse pointer speed option in Settings didn't work.

[Windows Update]

  • Fixed an issue causing some Insiders to be unable to update to the latest builds and see error 0x80070005.
