4 more open applications to optimize MS Windows – Part 3
Last month (July 2026), we brought you a second great compilation of open-source applications for optimizing MS Windows . And now, this month, to continue contributing to making Windows a more user-friendly and reliable operating system through tools from the Linux world, we offer you the third and final installment of the year on this topic, in which we'll introduce you to four more useful free and open-source applications for optimizing MS Windows : OptimizerDuck, Win11Debloat, Chris Titus Tech's Windows Utility, and PASPAS. This completes our list of the top 10 best applications to know and use during 2026.
However, before we begin, we think it's important to mention that in the first part of this post, we included the following three applications: Optimizer, Winhance, and WinTune . Of these, only Optimizer is currently not undergoing normal development . But in its place, there's now a cleaning and optimization application called OptimizerNXT . Both are from the same GitHub developer, Deadmoon ( Hellzerg). In the second part, we'll cover three more: Kudu , Sparkle , and WinScript . So, if you're a Linux user who, for whatever reason, still uses Windows, keep reading this post to learn how to better optimize and secure your Windows system.

And as usual, before delving into this interesting and useful post about these new "free, open-source applications for optimizing MS Windows ," in addition to Optimizer (OptimizerNXT), Winhance, WinTune, Kudu, Sparkle, and WinScript ; we recommend exploring the previous related post (part II) , after you finish reading this one:
The Linuxverse (the realm of free, open-source software and GNU/Linux) is not limited to the world of free and open-source distributions and operating systems, such as Linux and BSD. It also represents an important and even fundamental part of the ecosystems of proprietary, closed, and paid operating systems, such as macOS and Windows.

OptimizerDuck
OptimizerDuck is a multilingual, open-source, simple yet powerful Windows operating system optimization tool, created by and for the community, that helps users clean, tweak, and optimize any computer more easily than ever before. It's a free and open-source tool designed to offer performance, privacy, and simplicity when used to optimize Windows. Optimization, in this context, refers to reducing unnecessary load, allowing your Windows computer to dedicate more resources to what truly matters. This is crucial because whether you're gaming, programming, creating content, or simply browsing the internet, a well-optimized Windows system feels faster and more responsive.

Win11 Debloat
Win11Debloat is a small, open-source, and well-designed tool—the kind a friend would create for their friends—that helps you take back control. It was developed by an amazing programmer, Jeffrey, popularly known as Raphire. This tool is written in PowerShell and is compatible with Windows 11 and Windows 10. It's currently an open-source, graphical script that you run once (or whenever you want) and that, like magic, removes unnecessary software. And because it's open source, anyone can see exactly what's been added in each version, what changes have been made, and what it focuses on when solving problems and optimizing the operating system. Therefore, its main goal isn't to harm Windows, but to make Windows feel like yours, not someone else's. Explore the GitHub repository
Chris Titus Tech's Windows Utility (Winutil)
Chris Titus Tech's Windows Utility , also known as "Winutil," is a comprehensive PowerShell-based graphical tool that helps Windows users install applications (allowing for quick installation of popular software without manual downloads), apply tweaks (optimizing Windows for improved performance, privacy, and usability), troubleshoot problems (providing one-click solutions to common Windows issues), manage updates (controlling how and when Windows updates are installed), and access tools (providing quick access to Windows panels and utilities).

PASPAS
PASPAS is a comprehensive visual utility for cleaning temporary files, reviewing registry entries, uninstalling programs, and optimizing Windows performance. It offers users great and useful features such as: an efficient, multi-level cleaning tool for the operating system (scans and removes temporary files, system logs, memory dumps, and preload data); a helpful Windows registry scanning tool (scans nine specific registry categories for orphaned entries and invalid file paths, then allows the user to manually review and remove only what they want, among other capabilities); an effective program uninstallation tool (capable of quickly detecting, selecting, and uninstalling installed software); and finally, an operating system optimization tool (allowing modifications to the registry and services to improve privacy and performance).
