A Windows system tray application that shows whether the system proxy is enabled.

This is a Windows port of the macOS ProxyStat application.

• System Tray Icon: Shows proxy status at a glance
  • 🟠 Orange icon: Proxy is enabled
  • ⚫ Gray icon: Proxy is disabled
• Instant Updates: Responds immediately to proxy setting changes (no polling)
• Quick Access: Double-click or right-click to access proxy settings
• Context Menu:
  • Open System Proxy Settings
  • Quit

• Windows 10/11
• No runtime required (self-contained executable)

• .NET 10.0 SDK (for building only)

cd ProxyStat
dotnet build

dotnet run

dotnet publish -c Release

The executable will be in bin/Release/net10.0-windows/win-x64/publish/ProxyStat.exe

The app reads the Windows proxy settings from the registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

It uses RegNotifyChangeKeyValue to watch for changes — no polling, instant response when proxy settings change.
