Windows LockUp is a computer security software, which enables you to apply password protection to Windows and restrict others from being able to use your PC while you are away. It starts automatically with Windows and optionally locks your desktop upon loading. It hides your desktop at the same time and shows a picture, which you can change in the options. An allowed time schedule and duration can be defined for each user to restrict access to your PC in definite hours. Windows LockUp also supports monitor power save options and has some additional useful features like built-in password protected screen saver and network user validation feature for Windows logon to increase your security. You will find the program interface very easy to negotiate. Excellent online help is available.
