Shutter 4.8

Shutter 4.8: Tiny, Powerful Windows Shutdown Scheduler

Shutter 4.8 is a free, portable (no-install) utility that lets you automate almost any power-related action on Windows with extreme flexibility. Released in 2023 by Denis Kozlov, this lightweight tool (~1 MB) remains one of the simplest yet most effective ways to shut down, restart, sleep, hibernate, lock, or log off your PC exactly when you want — without needing Task Scheduler or third-party scripts.

Main Features

• Countdown timer (e.g., “Shut down in 30 minutes”)
• Specific time scheduling (“Restart at 03:00 AM”)
• Trigger actions based on events:
  • CPU usage drops below X% for Y minutes (perfect for finishing downloads/rendering)
  • Network usage falls under a threshold
  • Specific program/window closes or opens
  • Idle time exceeds X minutes
  • Battery level reaches critical/low
  • Internet connection lost or regained
• Multiple actions at once (e.g., hibernate + close lid + mute sound)
• Run programs or open websites before/after actions
• Hide the tray icon completely (stealth mode)
• Very low resource usage

Why It’s Still Loved in 2025

Unlike bloated alternatives, Shutter does one thing and does it perfectly: it gives you pixel-perfect control over when and why your PC powers off. Whether you want to save electricity after late-night torrents, auto-sleep when a render finishes, or silently lock the PC when you walk away, Shutter handles it quietly and reliably.

Lightweight, free, portable, and actively maintained — Shutter 4.8 is still the gold standard for automated shutdown tools. Download it once and forget it’s even running — until your PC turns off exactly when you told it to.
