InstallerClean review
A focused, open-source utility for finding and removing orphaned MSI and MSP files.
Reviewed by iTechGuides Editors · Editorial team · Updated Sep 2026
InstallerClean is an open-source Windows utility for identifying orphaned files in the hidden C:\Windows\Installer folder. It scans MSI installers and MSP patches, checks Windows Installer and registry records, and detects files that are no longer needed, including superseded patches. The product is intended for Windows users and administrators who need to reclaim disk space without manually deleting installer-cache files. It is a focused cache-cleanup tool rather than a general application uninstaller.
InstallerClean uses an open-source pricing model and includes a free plan. The free offering includes the scanning and cleanup workflow, with options to move removable files to a user-selected backup folder or permanently delete them. It also provides setup and portable builds, plus a command-line tool for scripting and scheduled tasks. Release downloads include published SHA-256 hashes, giving administrators a way to check downloaded files against the vendor's published values. The Windows 10 category specification and portable version support make it suitable for supported Windows systems where installation flexibility matters.
The product's narrow scope is also its main limitation. InstallerClean works on the Windows Installer cache; it does not uninstall applications themselves. It also does not provide forced uninstall, batch uninstall, or install monitoring capabilities. Users looking for a broader uninstaller with application removal workflows should choose an alternative designed around uninstalling programs rather than cleaning orphaned MSI and MSP files. InstallerClean is a better fit when the specific task is reviewing installer-cache files, archiving removable items, or deleting them through a graphical or command-line workflow.
