CodeWinOptimizer

Windows optimization & customization tool — 171 apps, 140+ tweaks, real-time monitor, disk cleanup, network speed test, driver backup, and quick-apply tweak presets — all in a single portable .exe.

Built with Wails v2 — Go backend + HTML/CSS/JS frontend rendered in WebView2.

Auto-elevates to Administrator on launch. Most features (registry, DISM, bcdedit, WinGet) require admin privileges.

Antivirus notice: This tool uses PowerShell, DISM, WMI, and registry commands. Some antivirus may flag the .exe as suspicious (heuristic/AI false positives). All code is open source — review the source or build it yourself with wails build.

Quick Install

Open PowerShell as Administrator and run:

irm "https://codewinoptimizer.com/win" | iex

That single command downloads the latest release from GitHub to %TEMP% and launches it with elevation. No installation, no manual download — always the latest version.

Prefer a manual download? Grab the .exe from the latest release.

How to Run

Prerequisites

• Go 1.20+
• Wails v2
• Windows 10/11 with WebView2 runtime

Bundled third-party binary (required for build)

The app embeds O&O ShutUp10++ at compile time via //go:embed assets/OOSU10.exe so the "ShutUp10++" toolbar button works out of the box. The binary is not redistributed in this repo (third-party freeware, .exe is in .gitignore).

If you build from source, download it manually before running wails dev or wails build:

1. Download OOSU10.exe from the official site: https://www.oo-software.com/en/shutup10
2. Place it at assets/OOSU10.exe (create the assets/ folder if missing)
3. Then run wails dev / wails build as usual

Without this file the Go compiler will fail with pattern assets/OOSU10.exe: no matching files found.

Development (live reload)

wails dev

Build executable

wails build

Output: build/bin/CodeWinOptimizer.exe

Usage

1. Run CodeWinOptimizer.exe as Administrator
2. (Recommended) Create a restore point first — type a name and click "Create Restore Point"
3. Use any tab: install apps, apply tweaks, run features/fixes
4. All operations are logged in the terminal
