Windows version, edition, and architecture
Windows 11 Home, version 25H2, OS build 26200.9168, x64
Describe your issue
UniGetUI does not detect installed WinGet packages when Windows is using Japanese as the display language.
The WinGet CLI itself works correctly: winget list shows the installed packages normally. However, UniGetUI reports 0 installed packages from WinGet.
If I change the Windows display language to English, sign out and sign back in, UniGetUI detects the installed WinGet packages correctly.
Changing the Windows display language back to Japanese causes the issue to return.
This may be related to UniGetUI parsing localized WinGet CLI output.
Steps to reproduce the issue
- Set the Windows display language to Japanese.
- Sign out of Windows and sign back in.
- Run
winget list in PowerShell.
- Confirm that WinGet correctly lists the installed packages.
- Open UniGetUI.
- Go to the Installed Packages page.
- Reload the package list.
- Observe that UniGetUI reports 0 installed packages from WinGet.
Then:
-
Change the Windows display language to English (United States).
-
Sign out of Windows and sign back in.
-
Run winget list again and confirm that the output is now in English.
-
Open UniGetUI.
-
Go to the Installed Packages page and reload the package list.
-
Observe that WinGet packages are now detected correctly.
-
Change the Windows display language back to Japanese, sign out and sign back in, and repeat the test.
-
Observe that the issue returns.

Relevant information
The issue appears to depend on the Windows display language.
On the same system and with the same WinGet version (v1.29.290):
- With the Windows display language set to Japanese, UniGetUI reports
Found 0 installed packages from Winget.
- With the Windows display language set to English (United States), UniGetUI reports
Found 202 installed packages from Winget.
In both cases, UniGetUI is using WinGetCliHelper() / CLI parsing, and the WinGet subprocess commands such as winget list --accept-source-agreements complete successfully with return code 0.
The WinGet CLI itself works correctly in both language environments and lists installed packages normally.
Because changing only the Windows display language changes whether UniGetUI can detect the installed packages, this appears to be related to localized WinGet CLI output parsing.
A similar issue exists in #4362, where installed WinGet packages are missing even though winget list works, but that issue appears to involve the native WinGet/COM API rather than this localized CLI parsing behavior.
Screenshots and videos
Installed Packages in Japanese: WinGet packages are missing, while Scoop and Chocolatey packages are detected.
Installed Packages in English (United States): WinGet packages are detected normally.
Please confirm these before moving forward
UniGetUI Version
2026.2.7
Windows version, edition, and architecture
Windows 11 Home, version 25H2, OS build 26200.9168, x64
Describe your issue
UniGetUI does not detect installed WinGet packages when Windows is using Japanese as the display language.
The WinGet CLI itself works correctly:
winget listshows the installed packages normally. However, UniGetUI reports 0 installed packages from WinGet.If I change the Windows display language to English, sign out and sign back in, UniGetUI detects the installed WinGet packages correctly.
Changing the Windows display language back to Japanese causes the issue to return.
This may be related to UniGetUI parsing localized WinGet CLI output.
Steps to reproduce the issue
winget listin PowerShell.Then:
Change the Windows display language to English (United States).
Sign out of Windows and sign back in.
Run
winget listagain and confirm that the output is now in English.Open UniGetUI.
Go to the Installed Packages page and reload the package list.
Observe that WinGet packages are now detected correctly.
Change the Windows display language back to Japanese, sign out and sign back in, and repeat the test.
Observe that the issue returns.
