ThemeToggle is a lightweight command-line utility for switching Windows between light and dark themes. It is designed for shortcuts, scripts, hotkeys, and scheduled automation, completing a switch in a few tens of milliseconds even on a busy desktop.
Features:
CLI operations for /toggle, /light, and /dark
Silent direct execution without requiring wrapper scripts
Automation-friendly flags such as /quiet, /passthru, and /exitcode
Compatibility refresh handling for apps that ignore standard theme broadcasts
Multi-monitor taskbar support
Windows 10 and Windows 11 support
Standalone executable and portable ZIP distribution
No runtime dependencies
What's new in 1.6.0
1.6.0 makes exit codes and theme-refresh behavior match measured reality:
Exit code 20 (broadcast failure) is now meaningful; it was chronically returned on successful theme changes because internal per-window notifications always failed silently
Faster switches: app nudges now run before the global broadcast, roughly halving in-process work on busy desktops
The stubborn-app nudge list is slimmed to notifications that verifiably deliver (Explorer, dialogs, Chromium/Electron family, Firefox)
/passthru now prints per-stage timing diagnostics
No CLI syntax changes; scripts keying on exit codes now get a real signal
A switch completes in a few tens of milliseconds even on a busy desktop.

1.5.5 focuses on direct execution and release quality:
Installer shortcuts and setup flows now launch ThemeToggle.exe directly
GUI launches stay silent; /notify remains a backward-compatible no-op
Release workflow now submits CI-generated WinGet manifests to avoid hash drift
WinGet metadata and validation were updated for the new packaging flow
Observed toggle duration on test systems remains around 10-15 ms.
