Best PC Junk Cleaners for Windows 10/11 in 2025

Introduction

Does your PC feel sluggish or low on space? You’re not alone. Over time, every Windows computer accumulates junk files—temporary caches, system leftovers, browser debris—that slow things down. While Windows 10 and 11 offer built-in cleanup options, third-party tools often provide quicker, more automated solutions. In this post, we’ll explore both manual methods and the best free and paid junk cleaner tools for 2025, including a bonus GitHub script you can run with a single click.

Clean Windows 10/11 Without Third-Party Software

Before downloading extra apps, know that Windows already provides built-in cleanup features:
