Abhinash you have not specified which property you want to lock. Anyway its easy and does not require any extra software to do this. Use the Windows Key (right of your space key) and press the L (lock) key simulatenously. Windows XP includes a new Microsoft Natural Keyboard shortcut to lock your computer. Any other compatible keyboard that includes the Windows logo key and the Application key can also perform this task.

If you are concerned your child may be spending too much time online or playing games this type of software will offer a solution. It allows you to set limits on how much time your child spends on the computer or online. You can share the same computer among your children by setting an individual time table for each child.
