The problem: In the special education classrooms I work in, students sometimes interrupt computer presentations from the teacher by randomly hitting the teacher’s computer keyboard. With this software, the keyboard and mouse are locked until a special key combination is pushed, for example: Ctrl-Alt-F. So now teachers can easily unlock their computers and they are immune to “fly-by” keyboard tapping.
To get around this problem, I got this free Windows software utility approved for use in my school district.
Here it is: BlueLife KeyFreeze v1.4
Just in case, here is a local copy of the Bluelife KeyFreeze 1.4.
It is free software and works well. It works great “out of the box” but want to open up the Options page on the system tray to set it just how you like it. I turned off the cute lock/unlock “music” and customized it to how I like it.
Installing it takes a couple steps (I’m not complaining, it’s totally free software!), I’ll walk you through it.
1 – Download and unzip BlueLife KeyFreeze
2 – It doesn’t install itself, it just runs when you double-click on it. I copied all the files to a new folder named C:\Programs\Keyfreeze
3 – You should make it start automatically when Windows starts. Here’s how to do that: Go to the C:\Programs\Keyfreeze folder and create a shortcut to KeyFreeze_x64.exe by right-clicking on it. Hit Win+R. Type “shell:startup” to open up the Windows startup folder. Drag the shortcut you just made into that folder. Done!
For difficult classroom situations, you might want to disable the touch-screen and the “turn computer off when closing the lid” features:
– On my computer, here’s how to disable the touch-screen. Hit the Windows key, type “Device manager”, find the “Human Interface Devices”, find the “HID Compliant touch screen”, Click the “driver” tab, click “Disable Device”. You can re-enable the touch screen by coming back to this page and clicking “Enable Device”
– To disable the “Turn off the computer when closing the lid” feature, hit the Windows key, type “change what closing the lid does”, Change “When I close the lid” to “do nothing”.
I’d love to hear in the comments if this software was useful in your classroom!
