ClockLock will let you take control over the user time and set rules for users and be assured that they are followed.
    Be assured that your security and user restrictions are not breached by anyone henceforth. This access control utility will help you to keep a control over the time spent by any other user on your PC. This program allows you to set time limits and will disallow any user to access the system beyond the time set. It further prevents restricted users from being logged on to the system in the restricted time. The tool seamlessly interacts with your windows XP operating system enforcing the rules and restrictions as long as your system is running. Here you can specify how long the computer can be used and also define the users who can use the computer without any limits. Any unrestricted user can easily access the system from the start menu and check the status of the program.
    The tool also supports security features; no restricted user can succeed in modifying the user time restrictions.
