KeyFreeze

KeyFreeze is a simple application that requires no installation. With it, you can lock your keyboard and mouse simply by double-clicking the executable.

In just a few seconds, you won't be able to do anything on your computer. The classic ctrl-alt-delete combination is the only way to unlock it.

At first, KeyFreeze may not seem very useful, but it's nice to watch movies and videos without worrying about touching the keyboard or moving the mouse. It's also a great option if you want to keep small children from tinkering with your computer.
