Ensure that Nobody Is Using Your Computer While You’re Away by Locking the Keyboard and Mouse with The Help of This Straightforward, Lightweight, and Portable Application

Nowadays, most OSes offer pretty standard features for locking one’s computer if need be. However, in the case of Windows, locking the computer can be done directly from the start menu or by using the Win+L key combination.

While this feature and the usage of a password should be enough to ensure that your computer is secure from unauthorized access, it’s not exactly what one might call a bullet-proof method. If you’re looking for a bit more security, you might want to check out Keyboard and Mouse Locker.

Just as its name states, this is by no means an application that will guarantee the ultimate protection of your data, but rather deter people who want to use your computer when they shouldn’t even more by “locking” or disabling the keyboard and mouse. The effect can be nullified by entering a custom unlock key sequence.

Does not require installation

The first thing to note about this app is the fact that it’s a portable application. This means that you can take it with you on a normal flash drive everywhere you go and use it on basically any Windows computer without requiring you to perform installation procedures.

Do keep in mind, though, that the computer in question needs to have Microsoft Visual C++ Redistributable Package installed.

Easy to use, little security utility

Working with the application is incredibly straightforward. The utility boasts a minimalist GUI that allows you to choose the duration before the Lock procedure activates, as well as to choose the custom to unlock the key sequence of your choosing.

You are also provided with the option of having a helpful tooltip that displays the keys when the computer is locked, however, keeping it active might defeat the whole purpose of the app.


All in all, Keyboard and Mouse Locker is a simple application that allows you to add an extra layer of security when you leave your computer unattended. It’s easy to use, quite effective, and does not require advanced computer skills to be set up properly.
