Windows - Uninstaller leaves behind files and registry keys

[o-l-a-v]

Describe the bug

On Windows, the VSCodium EXE and MSI uninstaller leaves behind the %APPDATA%\VSCodium directory.

The EXE uninstaller also leaves behind a registry key in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\AppListBackup.

This is unexpected, especially as the EXE uninstaller asks:

---------------------------
VSCodium Uninstall
---------------------------
Are you sure you want to completely remove VSCodium and all of its components?
---------------------------
Yes   No   
---------------------------

Please confirm that this problem is VSCodium-specific

• This bug doesn't happen if I use Microsoft's Visual Studio Code. It only happens in VSCodium.

^ I don't see how the behavior of VSCodium vs. VSCode matters here. Fork or not: Uninstaller should remove everything, unless user is promted about keeping preferences and configuration.

Please confirm that the issue/resolution isn't already documented

• [*] I checked the Docs page and the Troubleshooting page and my issue is not mentioned there.

To Reproduce
Steps to reproduce the behavior:

1. Download latest VSCodium for Windows from releases.
   • EXE or MSI doesn't really matter.
2. Install VSCodium.
3. Uninstall VSCodium using Geek Uninstaller.
4. After VSCodium uninstaller is done, Geek Uninstaller will find mentioned leftovers.

Expected behavior

Uninstaller should remove everything, especially when it explicitly asks "remove VSCodium and all of its' components"?
