The Windows Lock function also hides the current contents of the screen, though, annoying if you want to leave a movie playing, or perhaps monitor the progress of some lengthy task you’re running. And that’s why might sometimes prefer KeyFreeze, which locks your PC but leaves the screen active, just as before.
The program is tiny -- a single 341KB executable -- and portable. There are no unwanted extras here, just unzip it and you’re ready to go.

If you’re thinking this doesn’t sound too secure, then you’re right. Leaving the screen visible in the first place means you’ll be giving away lots of information to anyone passing, and the Ctrl+Alt+Del is perhaps the first hotkey anyone will guess.
Then again, KeyFreeze isn’t pretending to be a security tool. It’s not about protecting your system from attack, rather just reducing the chance of small children, perhaps wandering pets from knocking the mouse or keyboard and causing problems. And it does this very well.

For the most part, though, KeyFreeze is very effective, and if you need to protect your PC from curious kids then we’d give it a try.
