The best key logger application on a windows machine would be keystroke spy. This is a small windows application which will not be viewable in the windows task manager.

You can download this software from the link below.

If you are on a corporate PC, you will not be able to install the Keystroke spy as the anti-virus will be able to stop the installation.

Before installing the application, you should turn off your anti-virus application.

I’m currently testing this application and more reviews in future posts on how to use it and how to uninstall it.
