• I have not been informed if the issue is resolved in a preview version of the winget client.

Category of the issue

Installation issue.

Brief description of your issue

I couldn't upgrade Notepad++ because my elevated user could not access my current users $env:TEMP\Winget folder.

I run winget upgrade --id Notepad++.Notepad++ --exact as a non Administrator ( e.g. not in the Administrators group). winget writes out the npp installer to $env:TEMP\WinGet. The UAC prompt asks me to elevate which I do as another local user. The upgrade fails because it can't touch the aforementioned folder. This folder's permissions are automatically set and reset upon each run to only be accessible by SYSTEM or the current user.

Steps to reproduce

winget upgrade --id Notepad++.Notepad++ --exact as a non-Admin user and then elevate with a different local user.

Actual behavior

Installer fails with a pop-up that it can't access the path.

Expected behavior

Upgrade should complete successfully.

Workaround

I used add-localgroupMember -Member 'user' -Group 'Administrators' and then did winget upgrade and then remove-localgroupmember -Member 'user' -Group 'Administrators'.

Start by reproducing winget upgrade --id Notepad++.Notepad++ --exact as a non-Administrator user, then elevate with a different local user and inspect the diagnostic logs in %LOCALAPPDATA%\Packages\Microsoft.DesktopAppInstaller_8wekyb3d8bbwe\LocalState\DiagOutputDir. Done means the Notepad++ upgrade completes without granting the original user temporary Administrator membership.
