PC-Time Manager is an application capable to block your computer when the time your children are available to use it is over. It comes with a wide range of possibilities to modify your computer settings and keep an eye on them while they are surfing in the internet. It is also capable to keep a record of the conversations they hold while they are chatting in AOL, ICQ and MSN. It will protect its configurations with a password and the computer will only be able to turn on with a correct keyword. It is available in two languages and is compatible with all versions of Windows.
