No installation required. You can run RCleaner v44 Verified directly from a USB drive. This is ideal for IT technicians or users who don’t want persistent background processes.

Once installed, open the application and navigate to Help > About. The verified build will display a "Verified Build" watermark and a unique build number (e.g., 44.0.2.119). Unverified clones either fake this (poorly) or omit it entirely.

| Action | Result | |--------|--------| | Installation | Default installation attempts to change browser homepage to a low-authority search portal. | | Quick Clean | Deletes critical Windows prefetch files, causing slower boot on next restart. | | Registry Clean | Labels dozens of harmless registry keys as “critical errors,” then demands payment to fix them. | | Uninstallation | Leaves behind scheduled tasks that re-prompt for “upgrade to v44 verified.” |
