ClearLock provides a convenient way to lock your desktop with a transparent layer, allowing you to see what’s happening on your desktop and at the same time prevent access to the computer without the proper password. ClearLock comes as standalone executable, just run it, set your password and click the ClearLock icon whenever you want to lock your screen. To reset your password, simply delete the .ini file that was created in the same folder. ClearLock is designed to prevent others (e.g. your kids) from casually messing with your desktop, while keeping your desktop visible at the same time (unlike the Windows CTRL+L function), the program is NOT intended to be used as a security system – computer savvy users can bypass the lock.
