Summary:
Hope this helps anyone else running into this—this one is tricky because it survives reinstall unless AppData is cleared.
UltraEdit may unexpectedly switch to a Chinese UI after updating via WinGet. This is not caused by Windows language settings or malware. The root cause is a WinGet package issue that installs a Chinese-localized build, combined with UltraEdit persisting language settings in user profile data.
This has a bug report in winget <https://github.com/microsoft/winget-pkgs/issues/335903> which has been open since Feb 2.

Symptom
- UltraEdit launches in Simplified Chinese UI, even on an English Windows system (en-US)
- Persists after uninstall/reinstall
- May appear “random” or happen after reopening the app
- Only UltraEdit is affected (other apps remain English)
- The WinGet package for UltraEdit currently references a Chinese installer (ue_chinese_64.exe) despite indicating en-US locale
- When this version is installed or upgraded via WinGet, UltraEdit initializes in Chinese
- UltraEdit then persists this language setting in: %APPDATA%\IDMComp\UltraEdit\
- Subsequent reinstalls reuse this persisted setting, even when using the correct (English) installer
- Uninstall UltraEdit
- Delete:
%APPDATA%\IDMComp - Reinstall UltraEdit using the official English installer from:
https://www.ultraedit.com/downloads/ - Launch UltraEdit → UI should now be English
- Avoid using WinGet to install or update UltraEdit - Use the official installer or built-in updater instead
- Pin the package to prevent accidental upgrades: winget pin add IDMComputerSolutions,Inc.UltraEdit
- This is not malware or caused by Windows language settings or system locale
- Issue is reproducible and tied specifically to WinGet installation/update path
- A corresponding issue has been reported in the WinGet repository: https://github.com/microsoft/winget-pkgs/issues/335903
