Uninstall with winget
winget uninstall --id Ferdium.Ferdium --exact
The --id and --exact options are documented in Microsoft’s uninstall reference.
Check the result
Get-Process -Name 'Ferdium' -ErrorAction SilentlyContinue
winget list --id Ferdium.Ferdium --exact
Test-Path "$env:APPDATA\Ferdium"
No process output means only that the process is not running. A completed winget query with no match means this package is no longer listed; a query error does not prove removal. Test-Path returns True when the data folder remains and False when that path is absent. True is expected when keeping data.
What Mole lists
The review lists the program folder, shortcuts, the app’s protocol registration and startup entry as selected rows. %APPDATA%\Ferdium is unchecked, with measured disk caches listed separately as selected rows; the app’s own updater folder is also offered after removal. Keep the parent data folder when retaining service sign-ins and settings.
What this test covered
Recorded on 2026-10-03 for version 7.2.3, using vendor NSIS uninstaller.
Measured with a source test build in a Windows 11 ARM64 VM. Account sign-in, synced data and other installation channels were not tested. Delayed checks after an external uninstall are recorded separately; a Mole uninstall does not prove those checks.
