These are the fixes and improvements coming to the next update of Windows 10:

  • Improves several simplified Chinese fonts and the Microsoft Pinyin Input Method Editor (IME) to support GB18030-2022. You can enter and display characters from conformance level 1 or 2 using the additions to Microsoft Yahei, Simsun, and Dengxian. This update now supports Unicode Extensions E and F in the Simsun Ext-B font. This meets the requirements for level 3.
  • Adds many new features and improvements to Microsoft Defender for Endpoint. For more information, see Microsoft Defender for Endpoint.
  • You can now authenticate across Microsoft clouds. This feature also satisfies Conditional Access checks if they are needed.
  • Addresses an issue that affects the on-screen keyboard. The issue stops it from opening after you lock the machine.
  • Addresses an issue that affects a scheduled monthly task. It might not run on time if the next occurrence happens when daylight savings time occurs.
    Addresses an issue that affects all the registry settings under the Policies paths. They might be deleted. This occurs when you do not rename the local temporary user policy file during Group Policy processing.
  • This update affects the Desktop Window Manager (DWM). It improves its reliability.
  • Addresses an issue that affects .msi files. A minor update is not installed. This occurs when you use the EnterpriseDesktopAppManagement configuration service provider (CSP) to distribute the .msi file.
  • Addresses an issue that affects the Spooler service. It stops working. This issue occurs when you print using a certain workspace.
  • Addresses an issue that affects a tib.sys driver. It does not load. This occurs when HyperVisor-protected Code Integrity (HVCI) is enabled.
  • Addresses an issue that affects NCryptGetProperty(). When you call it with NCRYPT_KEY_TYPE_PROPERTY, the system returns 0x1 instead of 0x20. This occurs when the key is a machine key.
  • Addresses an issue that affects HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders. You can now set and maintain the correct default permissions for this directory path. When the permissions are wrong, the Start menu, search, and Azure Active Directory (Azure AD) authentication fail.
  • Addresses an issue that affects those who enable the “Smart Card is Required for Interactive Logon” account option. When RC4 is disabled, you cannot authenticate to Remote Desktop Services farms. The error message is, “An authentication error has occurred. The requested encryption type is not supported by the KDC.”
  • Addresses an issue that affects HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders. You can now set and maintain the correct default permissions for this directory path. When the permissions are wrong, Start menu, search, and Azure Active Directory (Azure AD) authentication fails.
