InstallerClean v1.9.0

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 v1.9.0 Release Notes:

What's changed

  • The command-line tool is now its own download. installerclean-cli.exe is a single self-contained exe, no install, nothing left behind, for scripting and deployment. (It already shipped inside the setup; now you can grab just the one file.)
  • Better help if a file ever goes missing from C:\Windows\Installer. A new README section explains, in Microsoft's own words, how that can happen (never from InstallerClean) and how to get the file back, and the app now flags a registered file that's missing from disk with a note on restoring it.
  • The README is now in seven languages (French, Spanish, Simplified Chinese, Japanese, Brazilian Portuguese and Russian, alongside English).
  • Improved Narrator and Voice Access support and full keyboard operation, and the app now follows the Windows reduced-motion and text-size settings.
  • Delete now checks the Recycle Bin is usable. If it isn't, you're asked how to proceed (move the files instead, delete permanently, or cancel).
Full per-change detail is in the changelog.

Downloads

  • InstallerClean-setup.exe (~90 MB) - Inno Setup installer; handles uninstall via Add/Remove Programs. Includes the command-line tool.
  • InstallerClean-portable.exe (~65 MB) - Self-contained single executable. Copy to a USB stick, run, done.
  • installerclean-cli.exe (~38 MB) - The command-line tool on its own. Self-contained, no install, nothing left behind. For scripting, scheduled tasks and deployment.
The portable is back to its compressed ~65 MB shape this release, about half the size it was in v1.8.2. The setup, portable and CLI builds bundle the .NET 10 runtime so nothing else needs to be installed. The slim build is for machines that already have .NET 10. All require administrator privileges and Windows 10 or 11. Or via Scoop:

Key Features of InstallerClean

  • Leftover File Detection
    InstallerClean scans your system for files and folders that remain after uninstalling applications. This helps free up disk space and reduce clutter.

  • Registry Cleanup
    It can identify unused or orphaned registry entries related to removed programs, helping maintain system organization.

  • Simple Interface
    The tool is designed to be straightforward. Users can scan and clean with minimal steps, making it accessible even for non technical users.

  • Portable Usage
    InstallerClean often runs as a portable application, so you can use it on multiple systems without installation.

  • Fast Scanning
    The scanning process is quick and does not heavily impact system performance.

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.

Pros

  • Lightweight and fast

  • Simple and easy to use

  • Helps remove leftover files and registry entries

  • Portable and convenient

Cons

  • Limited advanced features

  • Not as comprehensive as full system cleaners

  • Requires careful review before deleting files

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.
