"Hi Lawrence. How can I remove, hide and lock the system time so that my kids cannot set and change the time settings? Or simply Add a Restriction. Please explain it one-by-one. Because of it, they can hack and get around the Parental Time Control Limits. Thanks in Advance - Chris"
Disable or Hide the Clock icon in the Notification Area (Taskbar)
1. To hide the clock by using the Group Policy (gpedit.msc) which is applicable for some version Windows XP and Vista but not all:
Open gpedit.msc and go to the path below:
User Configuration > Start Menu and TaskBar > Remove Clock from the System Notification Area > Choose Enabled and click the Apply button
2. To hide the Clock by using the Registry Editor, go to the path below: ALL USERS
Right-Click > New > DWORD Value
Type HideClock > Double-click and input 1 > Reboot your Computer
Finally, This will prevent the clock from being displayed.
Problem (How to Hack): By using this, a smart kid can easily access or get around by using the command prompt or Start menu search and launching timedate.cpl or running this command: control.exe /name Microsoft.DateAndTime -> Windows Vista only
Quick Solution: Disable the Control Panel

"This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator"
