InstallerClean v3.4.0

InstallerClean is a small Windows tool that helps detect and remove leftover files, folders, and registry entries created by installed software. It is built for users who want to keep their system clean without manually digging through directories.

InstallerClean is a focused utility designed to clean up files and traces that remain after uninstalling programs. While many uninstallers remove the main application, leftover data often stays behind. InstallerClean aims to fix that with a simple and lightweight approach.

The application is typically portable, meaning it can run without installation and does not add extra load to your system.

InstallerClean v3.4.0 Release Notes:

InstallerClean 3.4.0

InstallerClean now offers more of the spare installers it used to hold back.
  • Programs installed from a CD, a DVD, a disc image or a USB stick: their spare installers can now be offered, whether or not the disc or stick is in the drive during the scan. A spare named like the program's own installer is still kept
  • Programs installed without administrator rights, just for the Windows account InstallerClean runs as: their sources are now read and their spares judged like any other program's. A program installed that way by a different account still keeps its spares
  • A program whose source is an http or https web address no longer holds its spares back for that reason alone
  • A program installed for every user, with no saved installer and no list of sources, no longer holds its spares back where it records no folder it was installed from, or one that isn't the Installer folder
  • Reading an empty disc drive or card reader no longer brings up the Windows box saying "There is no disk in the drive", which could stall a scan until it was answered
  • The anonymous report now says which kind of source held files back, and how many of the account's own per-user programs were read. Like the rest of the report it names no program, file or account (the privacy policy lists what it holds)
The changelog has the full list.

Downloads

  • installerclean-cli.exe (~37 MB) - The command-line tool as a single executable, for scripting, scheduled tasks and deployment.
The apps are unsigned and freshly downloaded files carry the browser's mark, so on first run Windows SmartScreen will usually warn that the publisher is unknown. Click "More info", then "Run anyway".
Build it yourself Built with .NET SDK 10.0.112 from the v3.4.0 tag. The portable and the command-line tool are single-file builds published with compression on. Release builds are deterministic, so building that tag yourself, on that SDK and with those flags, gives you the same bytes and the same hashes for the portable and the command-line tool; the README's Checking the download itself section has the detail. The installer is a different case: Inno Setup packs it and stamps the build year into it, so don't expect its hash to match.

User Experience

InstallerClean is easy to use, with a minimal interface that focuses on functionality. It does not overwhelm users with advanced settings, which makes it suitable for quick maintenance tasks.

However, advanced users may find it lacks deeper customization compared to more comprehensive system cleanup tools.

Performance and Compatibility

The software performs efficiently and works on most Windows systems. It is lightweight and does not consume significant resources during scanning or cleaning.

Because it targets leftover files specifically, it complements rather than replaces full system maintenance tools.

  • Helps remove leftover files and registry entries

  • Portable and convenient

Cons

  • Limited advanced features

InstallerClean is ideal for users who frequently install and uninstall software and want to keep their system tidy. It is also useful for those who prefer simple tools over complex system utilities.

InstallerClean delivers a focused solution for removing leftover files after uninstallations. While it is not a full system optimizer, its simplicity and efficiency make it a valuable addition to basic PC maintenance tools.
