A transparent lock screen seems to be not so useful at first, but if you’re a kind of person who often forgets what you’re doing on your computer before you leave it, then this transparent lock screen might be just the right thing for you. By making it transparent, you can instantly see what is really happening behind the lock screen. Perhaps a virus is being caught, a download process is finished, and so on. Even if you don’t see it useful, it is perhaps a good thing to have it just to kill your boredom of looking the same lock screen over and over again.
It is ClearLock that makes your lock screen transparent. The first time you run the application, it will ask you to specify a password to lock screen. After that, you can simply lock screen just by launching the application. Beside the transparency stuff, you’ll also get a sound effect when you lock screen.
When the screen is being locked, you have 3 chances to type the correct password to unlock it. If you fail 3 times, you’ll have to wait around 5 minutes before you can enter another password. The application shows the number of, if there is any, failed logins when you unlock the screen.
ClearLock is a free, portable tool and it works with Windows 7. It should work with Windows Vista and XP as well, but I’m not sure of it because I only tested it on Windows 7. You can download ClearLock from the official homepage if you’re interested.
