WindowsCleaner
What it is
WindowsCleaner is a free, open-source Windows utility for cleaning, debloating, optimizing, and troubleshooting Windows 10 and 11 systems. Its PowerShell cleanup engine covers 106 targets across browsers, developer tools, applications, games, caches, disks, logs, Windows Update, and driver leftovers. A genuine -WhatIf dry run previews removals and estimates reclaimed space before changes. Safety features described by the project include path checks, System Restore points, risk tiers, and an explicit option for the irreversible Dangerous tier. The optimization engine provides 77 tweaks covering performance, privacy, debloating, and networking, while backing up previous settings for undo. A repair engine performs 43 health checks in eight categories, with scan-first operation and selectable repairs. WindowsCleaner offers a WPF desktop app, console menu, PowerShell scripts, and a dependency-free batch alternative. Unattended runs can produce logs and JSON reports, and scheduled weekly cleanup or monthly health scans can be registered. Automation options include GPO, SCCM, Intune, and Task Scheduler.
