Block Input is a small portable software program that can block both the computer mouse and computer keyboard for a certain period of time.

There may be special situations where you want to block all input devices from sending signals to the computer system.

In which situations might this come in handy? In all were mouse and computer keyboard usage might interfere with another process, be it statistical analysis or programs that react immediately on mouse or keyboard input and where this is unwanted.

This also comes in handy when you want to clean your keyboard or mouse, with the computer turned on, if your toddler or child startisto hammer away on the keyboard which they always seem so attracted to, or if you just spilled something on the keyboard or mouse, and need to clean things up without any key presses or mouse clicks or movement on the PC during that time.

Block Input

Block Input is a lightweight program that you can run from any location as it is portable and does not need to be installed. The software application is hotkey driven and will disable the input devices for the configured amount of time. All you have to do is press the hotkey, or use the program's system tray icon, enter the desired time in seconds, and hit the ok button afterwards.

The time that the computer mouse and keyboard are blocked can be defined in the program's options. There is also an option to change the hotkey that starts the blocking from CTRL Q to another if you prefer another one or if the default one interferes with another program.

The program displays a tooltip next to the mouse cursor that counts down the remaining seconds that all input devices are blocked on the computer system. The software program adds itself automatically to the Windows System Tray.

A right-click will open a context menu that provides links to the program's options. It uses roughly 4 Megabytes of computer memory while running and should be compatible with most versions of the Windows operating system.


You can use Block Input if you want to block keyboard and mouse from interacting with a Windows PC.
