Win11Debloat is a Windows 10/11 PowerShell toolkit designed to streamline and automate the 'debloating' process—removing unwanted preinstalled apps, disabling telemetry, and tweaking system settings. It supports both interactive and silent modes and is popular among sysadmins and privacy-focused users.

Win Debloat Tools is an open-source PowerShell-based toolkit designed to strip away unnecessary components, preinstalled apps, and services from modern Windows installations to create a leaner, more responsive operating system. It aims to re-imagine Windows as if it were installed in a minimal state, removing bloatware and optional features with minimal impact on core functionality, though it warns users to proceed with caution since changes can be extensive. The project supports both graphical and CLI execution flows that let users individually select tweaks or apply a broad “Apply Tweaks” preset that automates many optimizations at once. It typically creates a system restore point before making changes, and also logs actions for transparency so you can review what was done. Beyond simple removal of apps, it can optimize services, cleanup temporary system files, remove residual Windows.old folders, and generally reduce resource overhead for better performance and battery life.
