About

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.
