Access Monitor

You might be looking for a program that lets you see who gets access to your PC, how long that person uses it, and what that person does. Most programs that do that also do more complex tasks, but if you're looking for something simple, Access Monitor is a great alternative. It's free, and uses a simple interface that's limited only to the features named above. This interface is accessible only if you have the administrator password. It lets you save all the information so you can check it later. From the settings menu you can change important options, like allowing it to open at startup, and choosing a password. All this makes Access Monitor a really useful application.
