InstallerClean
Open source tool to safely clean orphaned Windows Installer files and reclaim disk space
winget install --id=NoFaff.InstallerClean -e Description
InstallerClean safely reclaims disk space by removing orphaned files from C:\Windows\Installer, the hidden folder Windows never cleans up. It queries the Windows Installer API to find installers left behind by uninstalled software and patches replaced by newer ones, then lets you delete them to the Recycle Bin or move them somewhere safe. Free, open source, no telemetry.
InstallerClean is available through winget as package ID NoFaff.InstallerClean, with version 1.8.1. Use the install command above to set it up on Windows without downloading a separate installer manually.
