These are the fixes and improvements available with the latest update preview of Windows 10:
- Added improvements for servicing the Secure Boot component of Windows.
- Changed the timeout for Azure Active Directory (Azure AD) registration from 60 minutes to 90 minutes for hybrid Azure AD-joined Autopilot scenarios. This also addresses a race condition that causes an exception at timeout.

- Fixed an issue that causes Kerberos authentication to fail, and the error is “0xc0030009 (RPC_NT_NULL_REF_POINTER)”. This occurs when a client machine attempts to use the Remote Desktop Protocol (RDP) to connect to another machine while Remote Credential Guard is enabled.
- Fixed an issue that prevents you from changing a password that has expired when you sign in to a Windows device.
- Fixed an issue that might cause Windows to stop working when you apply a Windows Defender Application Control (WDAC) policy that doesn’t require a restart.
