Improvements

This security update includes quality improvements. When you install this KB:

• New! This update improves several simplified Chinese fonts and the Microsoft Pinyin Input Method Editor (IME). They now support GB18030-2022. Characters in the Standard Chinese Characters List (GB18030-2022 implementation level 2) are available in Microsoft Yahei (regular, light, and bold), Dengxian (optional font: regular, light, and bold), and Simsun. The Simsun Ext-B font (GB18030-2022 implementation level 3) now supports Unicode CJK Unified Ideographs Extensions E and F.

• New!  This update removes Simplified Chinese handwriting recognition from Windows Server 2022. This is because conformant handwriting recognition is not available for Windows Server. Updated media will have this change. To update existing images, use the DISM tool to remove the Simplified Chinese Handwriting capability.

• This update addresses an issue that affects console applications. They fail when you set the system locale to Japanese.

• This update addresses an issue that affects the Notepad combo box in Settings. It fails to show all the available options.

• This update addresses an issue that affects Microsoft Edge IE mode. The text on the status bar is not always visible.

• This update addresses an issue that affects the Microsoft HTML Application Host (HTA). This issue blocks code execution that uses Microsoft HTA. This occurs when you turn on Windows Defender Application Control (WDAC) User Mode Code Integrity (UMCI) enforced mode.

• The update addresses a random issue that affects svchost.exe. There is significant memory growth in a system. This occurs when svchost.exe contains the User Access Logging Service (UALSVC).

• This update 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.

• This update addresses an issue that affects Active Directory Users & Computers. It stops responding. This occurs when you use TaskPad view to enable or disable many objects at the same time.

• This update addresses an issue that affects File Explorer. It might stop responding indefinitely. This occurs after you try to view the effective access permissions for files in File Explorer.

• This update addresses an issue that affects Live Migration. It might fail in a stretch cluster deployment. This occurs because the Storage Replica fails to retry after it receives a retry error from the Cluster API.
