What WindowsCleaner is

WindowsCleaner is a free PowerShell utility for cleaning, debloating, optimizing, and troubleshooting Windows 10 and 11. Its cleanup engine covers 106 targets, including browsers, developer tools, apps, games, system caches, disks, logs, Windows Update, and driver leftovers. A -WhatIf dry run previews proposed removals and estimates reclaimed space. The project describes path safety checks, System Restore points, and risk tiers; the Dangerous tier requires an explicit option and can make irreversible changes. Its optimization engine includes 77 tweaks for performance, privacy, debloating, and networking, with previous settings backed up for undo. A repair engine runs 43 health checks across eight categories and supports scan-first operation with selectable repairs. Users can choose a WPF desktop app, interactive console menu, PowerShell scripts, or a dependency-free batch cleanup alternative. It also supports unattended runs with logs and machine-readable JSON reports, plus scheduled weekly cleanup and monthly health scans. Automation options named by the project include GPO, SCCM, Intune, and Task Scheduler. The README requires Administrator access and PowerShell 5.1 or later, with PowerShell 7 or later recommended.
