CodeWinOptimizer

Windows optimization & customization tool — 171 apps, 140+ tweaks, real-time monitor, disk cleanup, network speed test, driver backup, and tweak profiles — 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.
