KB4038801

Microsoft recently rolled out one major cumulative update for Windows 10 Anniversary UpdateKB4038801 doesn’t bring any new operating system features, but it does include a long list of bug fixes that will definitely make the OS more stable and reliable.

Without further ado, we’ll list the complete update changelog below.

KB4038801 fixes and improvements

  • Updated the BitLocker.psm1 PowerShell script to not log passwords when logging is enabled.
  • Addressed issue with the Lock Workstation setting for smart cards where, in some cases, the system doesn’t lock when the smart card is removed.
  • Addressed issue where saving a credential with an empty password to Credential Manager causes the system to stop working when attempting to use the credential.
  • Addressed issue where an access token is improperly closed from a WMI query.
  • Addressed issue where the size of a cloned file was improperly calculated by ReFS.
  • Addressed error STOP 0x44 in Npfs!NpFsdDirectoryControl.
  • Addressed error 0x1_SysCallNum_71_nt!KiSystemServiceExitPico.
  • Addressed issue where a computer loses access to its domain each time a Managed Service Account (MSA) automatically renews its password. 
  • Addressed RemoteApp display issues that occur when you minimize and restore a RemoteApp to full-screen mode.
  • Addressed issue with delays when accessing Office documents from a remote network drive. Files open, but file access and file saves are affected.
  • Access delays increase dramatically with increased file size.
  • Addressed issue to prevent user logon delays. 
  • Addressed issue where the Get-AuthenticodeSignature cmdlet does not list TimeStamperCertificate even though the file is time stamped.
  • Addressed issue that may occur when you inspect a corrupted VHDX file on a Hyper-V host; the error is “Multiple Bugcheck BAD_POOL_CALLER (c2) 0000000000000007; Attempt to free pool which was already freed”. 
  • Addressed issue where the Remote Desktop’s idle timeout warning doesn’t appear after the idle time elapsed.
  • Addressed issue where revoking a certificate associated with a disabled user account in the CA management console fails. The error is “The user name or password is incorrect. 0x8007052e (WIN32: 1326 ERROR_LOGON_FAILURE)”.
  • Addressed issue where Multi-Factor Authentication doesn’t work correctly with mobile devices that use custom culture definitions.
  • •Addressed issue where the cluster node stops working when using async replication on very high-speed disks.
  • Addressed issue where ksecdd.sys causes LSASS to leak kernel memory in paged pool. This most commonly affects servers that host an HTTPS service and handle a heavy load of TLS handshakes from clients.
  • Addressed issue with excessive memory usage in LSASS when it evaluates an LDAP filter over a large record set on domain controllers.
  • Addressed issue where LSASS consumes large amounts of memory on 2012 R2 domain controllers during a security descriptor propagation operation. 
  • Addressed issue where console and RDP logons permanently stop responding at “Applying user profile settings” because of a deadlock between DPAPI/LSASS and RDR. Once the deadlock occurs, new logons fail until the logon computer is restarted.
  • Addressed issue where performing TPM-related operations using PowerShell commands on a virtual machine causes the TPM support to fail. For example, performing a Get-TPM operation produces the following error: “get-tpm : An internal error was detected. (Exception from HRESULT: 0x80290107). At line:1 char:1”.
  • Added support for OIDC logout using federated LDPs. This will allow kiosk scenarios where multiple users may be serially logged into a single device that has federation with an LDP.
  • Addressed issue with WinHello where CEP- and CES-based certificates don’t work with gMSA accounts.
  • Improved RPC reliability when sending large data blobs.
  • Addressed issue where using a smart card to log on to a Remote Desktop Server sometimes causes the server to stop responding.
  • Addressed issue where “Hibernate Once/Resume Many ” (HORM) could not be enabled on Windows Server 2016 IoT with Unified Write Filter.
  • Addressed issue where deleting an object that has many links in Active Directory causes replication to stop with Event 1084, error 8409: “A database error has occurred”. For additional information, read KB3149779.
  • Addressed issue where Windows Server 2016 domain controllers (DC) may log audit events with ID 4625 and 4776. 
  • Addressed access violation in LSASS that occurs during the startup of the domain controller role conditions. 
  • Addressed issue where Windows Server Essentials Storage Service stops working if a tiered virtual disk is created on a storage pool that has HDD and SSD.
  • Addressed issue where attempting to extend a Clustered Shared Volume (the source disk) beyond 2 TB using Disk Management in the Storage Replica feature of Windows Server 2016 Datacenter Edition fails.
  • Addressed issue where the Windows Internal Database (WID) on Windows Server 2016 AD FS servers fails to synchronize some settings because of a foreign key constraint.
