Windows 10 Insider Update Generic

Microsoft has released KB5011831 on the Release Preview channel for Insiders for Windows 10 21H2. The update does not include any new features but includes numerous improvements for the OS, which hints at getting ready for a “type c” optional release to the stable channel in the upcoming weeks.

Significant improvements to this flight will improve the operating system’s startup time, which can occasionally go up to 40 minutes! This would be a relief if you had to wait that long before your computer boots up.

Let us now discuss other improvements in this release before we see how to install it.

Updates and Fixes

  • Improvements have been made to servicing the Secure Boot component of Windows.
  • Microsoft has changed the timeout for Azure Active Directory (AAD) 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.
  • An issue that causes a remote desktop session to close or a reconnection to stop responding while waiting on the accessibility shortcut handler (sethc.exe) has been fixed.
  • An issue that delays OS startup by approximately 40 minutes has been taken care of.
  • An issue that incorrectly returns Execution Policy settings from the registry has been fixed.

  • An issue that causes Kerberos authentication to fail, and the error is “0xc0030009 (RPC_NT_NULL_REF_POINTER),” has been fixed.
  • An issue that prevents you from changing your password that expired when you sign in to a Windows device has been fixed.
  • An issue that could cause Windows to stop working when you apply a Windows Defender Application Control (WDAC) policy that doesn’t require a restart has been addressed.
  • An issue that might fail to copy the security portion of a Group Policy to a machine has been fixed.
  • An issue that causes the Key Distribution Center (KDC) code to incorrectly return the error message “KDC_ERR_TGT_REVOKED” during domain controller shutdown has been addressed.
  • An issue that could prevent Graphics Processing Unit (GPU) load balancing over Remote Desktop from working as intended has been fixed.
  • An issue that prevents the instantiation of the Microsoft RDP Client Control, version 11 and higher, inside a Microsoft Foundation Class (MFC) dialog, has been addressed.
  • An issue that could cause a Microsoft OneDrive file to lose focus after you rename it and press the Enter key has been mitigated.
  • An issue that causes the news and interest panel to appear when you haven’t clicked, tapped, or moused over it has been taken care of.
  • An issue that fails to pass the Shift KeyUp event to an application when you use the Korean IME has been fixed.
  • An issue that might occur when you use Netdom.exe or the Active Directory Domains and Trusts snap-in to list or modify name suffixes routing has been addressed.
  • An issue that displays the wrong IME mode indicator when the Font Mitigation policy is enabled is fixed.
  • The issue that causes the primary domain controller (PDC) of the root domain to generate warnings and error events in the system log is fixed.
  • An issue that affects the Multichannel connection of the Server Message Block (SMB) and could generate a 13A or C2 error is addressed.
  • An issue that occurs when you map a network drive to a Server Message Block version 1 (SMBv1) share is fixed.
  • An issue that damages the pool when the Client-Side Caching (CSC) cleanup method fails to delete a resource created is fixed.
  • An issue that could cause the server to lock up because the non-paged pool grows and uses all memory is addressed.
