About CodeWinOptimizer

CodeWinOptimizer is a free, open-source tool that helps you take control of Windows 10 and Windows 11: remove preinstalled apps, install software with WinGet or Chocolatey, apply documented system tweaks, free up disk space, monitor your hardware, and create restore points — all from a single portable .exe with no installation and no telemetry.

What the app does

• App Manager — install or uninstall 180+ curated apps across 8 categories using WinGet or Chocolatey, with a dynamic action button per app.
• System Tweaks — more than 120 tweaks across 14 categories (network, memory, GPU, privacy, telemetry, power, and more). Every tweak documents its exact commands, its impact level, and any warnings.
• Windows Features & Quick Fixes — enable or disable Hyper-V, WSL, Sandbox and others, and run common repairs like network reset and SFC/DISM scans.
• Disk Cleanup — clean temp files, the recycle bin, prefetch, the Windows Update cache, thumbnails, the DNS cache, and memory dumps.
• Startup & Services — see what runs at login and decide what should stay.
• System Monitor — a PC health score, hardware cards with live temperatures, per-host latency badges, and built-in network tests.
• Restore & Backup — system restore points, full registry backups, and driver backups, so changes can always be undone.

Why build another Windows optimizer?

Most optimizer tools ask you to trust them blindly. They are closed-source, bundled with offers, or they phone home behind your back. Windows has real annoyances worth fixing — telemetry, bloatware, resource-hungry background tasks — but fixing them shouldn't require running an installer full of adware or a mystery script from a forum.

CodeWinOptimizer takes the opposite approach: it is local-first (everything runs on your machine), portable (one .exe, works from a USB drive, nothing installed), and transparent (every tweak shows exactly what it changes and why, before you apply it). It is inspired by the excellent WinUtil project, with a friendlier interface and built-in safety nets.

Transparent by design

• Every tweak is documented with the exact commands it runs — you can review each one before applying it, and read the same commands in the online documentation.
• Every tweak lists its impact level and any relevant warnings, so you can make informed decisions.
• Before you start, the tool helps you create a system restore point, and it can back up the full registry and your drivers.
• The application is MIT-licensed open source. You can read the code, build it yourself, or suggest changes on GitHub.
• No telemetry: the app does not send usage statistics or personal data anywhere.

About this website

This website is the official home of the project. It contains the full documentation (every tweak, every feature), step-by-step guides for common Windows tasks, and download instructions. You can browse everything without an account, and the site itself runs no analytics or tracking scripts.

Hosting and maintenance are paid for with advertising served through Google AdSense, along with voluntary support from users. Ads never influence the documentation — a tweak is included because it works, not because anyone paid for it.

Who is behind it

CodeWinOptimizer is designed and developed by OscarDev, an independent developer who builds open-source tools for Windows. The project grows with feedback from its community: bug reports, feature requests, and pull requests are all welcome on GitHub.

Common questions

Is CodeWinOptimizer really free?

Yes. The application is free and open source under the MIT License. There is no paid tier, no account, and no locked features. Donations and the website's ads are what keep the project going.

Does it send telemetry?

No. The app runs entirely on your PC and does not send usage statistics, identifiers, or personal data to us or to third parties. Ironically, one of its most popular features is disabling Windows' own telemetry.

Is it safe to use?

The tool is used by thousands of people and it is built with safety nets: restore points, backups, documented commands, and impact levels. That said, any system tweak carries some risk — our documentation explains what each change does so you can decide, and we always recommend creating a restore point first and reviewing tweaks marked as high impact.

Which Windows versions are supported?

Windows 10 and Windows 11, 64-bit, with the WebView2 runtime (already included in current Windows versions). No installation is needed and nothing is left behind if you run it from a USB drive.
