1 Click and Lock is a security system for your PC, which lets you block the desktop to anyone who doesn+t have the password. It is a very useful tool so that no-one can use your PC without prior permission.You can configure 1 Click and Lock to start when your operating system starts, and so you just start Windows and the desktop, the toolbar and even the wallpaper are blocked. 1 Click and Lock has two ways to block: first, hiding all the Windows desktop behind a screensaver; two, letting everyone see the desktop, but only those with the password to access it.With the PC totally blocked, those who want to use it but don+t have the password can only leave a message via the application, saving the time, date and message author for you to later read. Its interface is very simple and intuitive so it will be easy for you to configure to your taste.
