What it is

WindowsCleaner is a free PowerShell cleaner, debloater, optimizer, and troubleshooting toolkit for Windows 10 and 11. Its registry-driven cleanup engine covers 106 targets across browsers, developer tools, applications, games, caches, disks, logs, Windows Update, and driver leftovers. A real -WhatIf run previews removals and estimates reclaimed space. Safety features described by the project include path guards, System Restore points, risk tiers, and a Dangerous tier requiring an explicit option. Optimization provides 77 tweaks for performance, privacy, debloating, and networking, with earlier settings backed up for undo. The repair engine runs 43 health checks in eight categories and supports scan-first, selectable repairs. WindowsCleaner is available as a WPF app, console menu, PowerShell scripts, and a dependency-free batch alternative. It supports unattended logs, JSON reports, and scheduled weekly cleanup and monthly health scans. Administrator rights and PowerShell 5.1 or later are required.
