改良と修正:

• New! Adds improvements for servicing the Secure Boot component of Windows.

• Changes 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.

• Addresses an issue that displays a black screen for some users when they sign in or sign out.

• Addresses 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.

• Addresses an issue that prevents you from changing a password that has expired when you sign in to a Windows device.

• Addresses 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.

• Addresses 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. These procedures might fail. The error message is, "Insufficient system resources exist to complete the requested service." This issue occurs after installing the January 2022 security update on the primary domain controller emulator (PDCe).

• Addresses an issue that displays the wrong IME mode indicator when the Font Mitigation policy is enabled.

• Addresses an issue that causes the primary domain controller (PDC) of the root domain to generate warning and error events in the System log. This issue occurs when the PDC incorrectly tries to scan outgoing-only trusts.

• Addresses an issue that affects a Server Message Block (SMB) multichannel connection and might generate a 13A or C2 error.

• Addresses an issue that occurs when you map a network drive to a Server Message Block version 1 (SMBv1) share. After restarting the OS, you cannot access that network drive.

• Addresses an issue that causes virtual computer object (VCO) password settings failure on a distributed network name resource.

• Addresses an issue that damages a pool when a Client-Side Caching (CSC) cleanup method fails to delete a resource that was created.

• Addresses an issue that might cause the server to lock up because the nonpaged pool grows and uses up all memory. After a restart, the same issue occurs again when you try to repair the damage.
