6. Child Lock
Child Lock has a useful Autolock function of allowing the computer’s keyboard and mouse to be locked after a 10 minute period of inactivity as well as the simple ability of instantly locking and unlocking using the keyboard combination of Alt+Home or Alt+End. It can also disable only the Windows control keys so if you want to lock a video into full screen for example, it can’t be Alt+tabbed out of. The tray icon has a small traffic light system of green, orange and red lights to determine the current mode you are in. Command line options are available.
Predator is a locking utility with a difference because instead of using a simple key combination or executable, it uses a USB drive to detect whether the computer should have keyboard, mouse and screen locks enabled. After you install the program, a key needs to be installed onto a USB drive. The drive is then polled every 30 seconds and if the key is not detected because the drive has been removed or the key has been deleted, the keyboard and mouse is locked with additional options of blanking/dimming the screen, hiding desktop icons, disabling autorun etc.
If you have a problem with your locking USB drive and key and you can’t unlock your computer, click on the locked screen and press Enter 3 times. This will bring up a window where you can enter the password you setup in the options window to gain access to the desktop and disable monitoring to reconfigure your settings. Some of the advanced options are disabled in the free version. Works on Windows XP and above, 32-bit and 64-bit versions are available.
8. Lock Windows
Of course, the easiest and quickest way to lock the keyboard and mouse down without using any extra software is by using the Windows Lock function. To get there just press Win key + L or go to Start and hover over the log off options arrow -> Lock. This does have a couple of drawbacks though; firstly you will need to create a password on your user account if you don’t have one or it’s very easy to get back in by simply pressing enter, and secondly if you’re playing a video or showing something on screen but don’t want the toddler to interact with the computer, it obviously won’t be seen.
