What is InstallerClean?
InstallerClean finds and removes unneeded files from C:\Windows\Installer, the hidden folder on every Windows PC that quietly accumulates installer copies and patch files. Windows never cleans this folder up. Disk Cleanup doesn't touch it. Over years it grows to tens of gigabytes, and on machines with Adobe Acrobat it can exceed 100 GB.
The app identifies two kinds of removable files: orphaned installers left behind by uninstalled software, and superseded patches that Windows has already marked as replaced but never deleted. It calls the Windows Installer COM interface directly to determine which files are no longer needed, rather than guessing from filenames or dates.
Safety is the default. Delete sends files to the Recycle Bin, so anything removed can be restored. Move copies files to a folder you choose, so you can keep them offline before committing. Nothing is touched until you confirm. Pending-reboot detection warns if Windows updates could affect the scan results.
InstallerClean is a modern open source alternative to PatchCleaner, which was last updated in March 2016.
InstallerClean is written in C# on .NET 8 with a WPF interface. MIT licensed, no telemetry, no account, no network activity unless you click Check for updates.
