Addresses an issue with zoom that occurs when using Microsoft Edge IE Mode on devices that use multiple high-DPI monitors.
Allows administrators to use a Group Policy to enable extended keyboard shortcuts, including Ctrl+S, for users in Microsoft Edge IE Mode.
Addresses an issue that might cause a deadlock when a COM server delivers an event to multiple subscribers in parallel.
Addresses an issue with Japanese input that occurs after focus changes between boxes in Microsoft Edge Legacy.
Addresses issue that causes 16-bit apps that run on NT Virtual DOS Machine (NTVDM) to stop working when you open them.
Addresses an issue with USB 3.0 hubs. A device connected to the hub might stop working when you set the device to hibernate or restart the device.
Addresses an issue that prevents users from adjusting or turning off the touchpad because of administrative settings.
Addresses an issue that displays nothing or shows “Computing Filters” indefinitely when you filter File Explorer search results.
Updates the Volgograd, Russia time zone from UTC+4 to UTC+3.
Adds a new time zone, UTC+2:00 Juba, for the Republic of South Sudan.
Addresses an issue with the Windows Event Log Forwarding client, which returns the first matching certificate without checking private key permissions. With this update, the Windows Event Log Forwarding client selects the client’s certificate only if the Network Service has read permissions for the private key.
Addresses an issue that causes PowerShell-based monitors to stop working when you enable transcription on the systems.
Addresses an issue that stops BranchCache from working if you activate Windows using Cloud Solution Provider (CSP) license.
Addresses an issue that prevents App-V applications from opening and generates error 0xc0000225.
Addresses an issue in which some machines enrolled with a mobile device management (MDM) service fail to sync if the device manufacturer's name contains a reserved character.
Addresses an issue with using a configuration service provider (CSP) policy to configure a custom setting for Audit Other Logon/Logoff events. The custom setting fails to take effect.
Updates the Open Mobile Alliance (OMA) Device Management (DM) sync protocol by adding a check-in reason for requests from the client to the server. The check-in reason will allow the MDM service to make better decisions about sync sessions. With this change, the OMA-DM service must negotiate a protocol version of 4.0 with the Windows OMA-DM client.
Addresses an issue with credential roaming that occurs when Windows Hello for Business is enabled.
Addresses an issue that prevents users from using the Remote Desktop Protocol (RDP) to connect to a Windows Server 2019 device that is in Desktop Experience mode.

Addresses an issue that causes a black screen or delays signing in to a Hybrid Azure Active Directory joined machine while the machine attempts to connect to login.microsoftonline.com.
Addresses an issue that prevents the Chromium-based Microsoft Edge from working. This issue occurs when Microsoft Edge is used in combination with Microsoft App-V and fonts are enabled inside the virtual environment.
Addresses possible race conditions that occur when the system calls NtOpenKeyEx(),which results in a stop error.
Addresses an issue with high memory usage when performing XSLT transforms using MSXLM6.
Addresses an issue that prevents Server Message Block 1 (SMB1) clients from accessing the SMB share after restarting the LanmanServer service.
Addresses an issue that might cause the cluster network interface to stop working for a short time. As a result, the network interface controller (NIC) is marked as failed. When the network is operational again, the system might not detect that the NIC is working and the NIC remains in a failed status.
Addresses an issue with signing in to a device that is in the current domain by using the default user profile of a device that is in a different, but trusted domain. The profile service of the current domain cannot retrieve the default user profile from the trusted domain and uses the local default user profile instead.
Addresses an issue with evaluating the compatibility status of the Windows ecosystem to help ensure application and device compatibility for all updates to Windows.
Addresses an issue that turns on Caps lock unexpectedly when using RemoteApp.
Addresses an issue with the svhost process that hosts the Microsoft-Windows-TerminalServices-LocalSessionManager. The svhost process consumes increasingly large amounts of memory because of a leak in COMMAND_ENTRY objects. Memory leaks might cause issues when signing in to an application or to the Remote Desktop. In extreme cases, the server might stop responding.
