Sparkle 2.21.1

Sparkle is a free and open-source Windows optimization utility designed to improve system performance, enhance privacy, and simplify PC maintenance. It combines a wide range of optimization and cleanup tools in a modern, user-friendly interface, making it easy to customize Windows for better speed and efficiency.

The application can remove unnecessary Windows apps and features, disable telemetry and other privacy-invasive components, clean temporary files, and apply performance tweaks to optimize system responsiveness. Sparkle also includes built-in utilities for running system maintenance tools such as SFC, DISM, and Check Disk, as well as a DNS manager and an integrated application installer powered by Winget and Chocolatey.

To help protect users, Sparkle can create system restore points before applying changes, allowing most optimizations to be reversed if needed. Regular updates and its open-source nature make it a powerful all-in-one toolkit for users who want greater control over their Windows installation while keeping their system clean, fast, and secure.
