A tiny Windows utility that keeps your PC and apps looking active while you step away. Set an interval, choose an invisible key, and AntiAFKPresser quietly taps it so your session never goes idle. No ads, no telemetry — a small .msi installer.
If you have been searching for an afk key presser download, this is the simple, ban-safe answer: a clean keep-alive tool that presses a chosen key at a fixed interval and, optionally, nudges the mouse and blocks sleep. It lives in the system tray and stays out of your way.
Idle timers are everywhere — screensavers, auto-lock, "away" status in chat apps, sleep and display timeouts. AntiAFKPresser sends a single, invisible keystroke on a timer so the system keeps seeing genuine activity. By default it presses F13, a real keyboard key that virtually nothing is mapped to, so the keep-alive tap has no visible effect on your documents, terminals or games.
- Invisible by default — presses F13 (or F15, or any custom key) through the Windows
SendInputAPI with hardware scan codes, so it registers as real input everywhere, including remote-desktop and full-screen sessions. - Simple interval — "Press every N minutes", adjustable from 30 seconds to 60 minutes.
- Optional 1px mouse nudge — a net-zero micro-move (right 1px, back 1px) for apps that watch the pointer as well as the keyboard.
- Keep Windows awake — an optional wake-lock (
SetThreadExecutionState) that blocks sleep, display-off and the screensaver while it runs. - One-click presets — Office, MMO and Corp PC set a sensible key + interval instantly.
- Tray-first — starts and stays in the system tray; closing the window keeps it running. Right-click the tray icon to toggle or exit.
- Big ON/OFF indicator — a clear status panel with a green dot when the keep-alive is active.
- Remembers your setup — settings are saved to
profiles.jsonand restored on the next launch. - Simple install — a small
.msipackage, runs on Windows 10 / 11 (.NET Framework 4.8, preinstalled).
AntiAFKPresser is a straightforward anti afk software windows helper. On each interval it:
- Injects one key down + key up for your chosen key via
SendInput(scan-code mode). - Optionally moves the mouse +1px then −1px so the cursor position is unchanged.
- Optionally re-asserts the "keep awake" wake-lock so the machine will not sleep or dim.
Nothing is injected into other programs and nothing reads another program's memory — the tool only generates ordinary keyboard and mouse input, exactly as if you had tapped the key yourself.
| Preset | Key | Interval | Mouse ±1px | Keep awake | Good for |

| MMO | F13 | 3 min | off | off | multi-game sessions and idle-sensitive clients |
| Corp PC | F13 | 2 min | on | on | a locked-down keep pc awake tool for managed machines |
