InstallerClean vs Wise Program Uninstaller

InstallerClean scans .msi and .msp files directly in C:\Windows\Installer to identify candidates for removal and reclaim disk space. It checks Windows Installer records and registry information, withholding files when those checks cannot establish that removal is safe. Users can move identified files to a chosen backup folder or delete them permanently. Downloads include portable, setup, and command-line builds; the setup option bundles the graphical interface and CLI. The command-line version supports scan, move, and delete operations for scripting and scheduled tasks, and reports exit codes and Windows Event Log events. InstallerClean is free and open source under Apache 2.0. It requires 64-bit Windows 10 version 1607 or later, or Windows 11, and administrator privileges. It does not scan subfolders or clean the WinSxS folder, and it has no background service, scheduled task, or automatic cleanup. Downloads are unsigned, so Windows may show an unknown-publisher warning; release pages provide SHA-256 hashes and VirusTotal scan results.

Wise Program Uninstaller removes Windows applications, including stubborn software, built-in apps and UWP programs. After a standard removal, its deep scan looks for leftover registry entries, orphaned files and empty folders. Force Uninstall searches for related files, folders and registry entries when Windows settings cannot remove an application. Custom Uninstall can target programs missing from Windows app lists if the user locates the installation folder. Software Health tools can clean leftover app data and temporary files, manage app permissions and services, and help control pop-ups and notifications. Batch browser-extension removal supports Chrome, Firefox, Edge and Internet Explorer. Downloads are listed for Windows 7, 8/8.1, 10 and 11 in 32-bit and 64-bit editions. A portable version is available; the maker recommends it for Windows XP because the installer no longer supports XP. The Free plan includes application removal, browser-extension removal, software-health analysis and premium technical support.
