CleanLock v2

Lock your keyboard and/or mouse while you clean them. Hold F12 for 5 seconds to unlock everything.

Run

1. Install AutoHotkey v2.
2. Save CleanLock.ahk as UTF-8 (no BOM is fine, ANSI is not).
3. Double-click it. The window appears.

Use

1. Pick Lock KEYBOARD, Lock MOUSE, or Lock BOTH.
2. Wait out the 3-second pre-delay. Click Cancel Pending to abort.
3. Clean.
4. Hold F12 for 5 seconds. A blue bar fills under the status text.
5. If you forget, the watchdog unlocks everything on its own (default 120s).

Why v1 did not work

Symptom in v1 ↕▾	Cause ↕▾	Fix in v2 ↕▾
−^!m did not unlock the mouse	The M key is inside the *vkXX block list. If the keyboard was also locked, ^!m could never fire	Removed. One universal escape: hold F12
Triple right-click unlock did nothing	Right-click was blocked by the same list, so ~RButton never got clean presses	Removed
Ctrl+Alt+Del did not unlock	Windows reserves it. No AHK script can block or hook it	Documented as impossible. Watchdog is the real fallback
Script crashed on start	Arrow functions assigned globals and silently created locals, so the watchdog timer never armed	All globals declared explicitly in every function

Known limits

• Ctrl+Alt+Del and Win+L cannot be blocked. Windows handles them in secure mode.
• The physical power button is unaffected.
• Devices with their own drivers (some gaming mice and touchpads) may pass input through AHK's hook.
• Elevated windows (Task Manager, UAC) do not receive blocked input from a non-elevated script. Run as admin if that matters.

Customize

Top of CleanLock.ahk:

HOLD_KEY    := "F12"    ; any key name: "Pause", "CapsLock", "F9"
HOLD_SECS   := 5
PRE_SECS    := 3
DEFAULT_WD  := 120

If you change HOLD_KEY, the block list automatically skips its VK, so the hold key keeps working.

Not a security tool

Anyone can press Ctrl+Alt+Del, open Task Manager, and end the script. This is a cleaning convenience tool, not access control.
