A few months earlier I showed you a crude but effective way to lock your PC using a USB thumb drive, without using any software. Now, I bring you another way to do this: this time using a software. It’s easier and more secure. Besides the software is free.
USB PC Lock Pro Turns any USB Flash Drive into a key that prevents unauthorized people from using your computer. USB PC Lock will automatically lock your computer and perform other actions when you step away from it.
# Lock worksation when you step away.
# Lock MSN Messenger.
# Stop streaming media traffic.
# Mute audio.
# Start/Stop event logger.
# Start/Stop batch.
