Traditional Chinese input method completely broken

July’s Patch Tuesday broke the Microsoft Changjie input method, rendering Traditional Chinese text input impossible on Windows 11 22H2/23H2. The spacebar stopped responding during character composition. The conversion candidate window refused to display. Users could not form or select words. For millions of Traditional Chinese users, their computers became incapable of typing in their language. The fix took two weeks to arrive in KB5062663, during which affected users had to find creative workarounds for the basic act of text input on a computer in 2025.
