Windows 7 - Time Zone - Allow or Prevent Users and Groups from Changing

   Information

This will show you how to allow or prevent specific users and groups from being able to change the computer time zone in Windows 7 and Vista.

You will need to be logged in as an administrator to do this tutorial.

   Note

Default Users and Groups Allowed to Change the Time Zone
NOTE: This user right determines which users and groups can change the time zone used by the computer for displaying the local time, which is the computer's system time plus the time zone offset. System time itself is absolute and is not affected by a change in the time zone.

On All Computers: Administrators, LOCAL SERVICE, Users

1. Open the Local Security Policy window, expand Local Policies in the left pane, and select User Rights Assignment. (see screenshot below)

2. In the right pane of User Rights Assignment, double click on Change the time zone. (see screenshot above)

3. Prevent Users or Groups to be able to Change the Time Zone
WARNING: Do not remove LOCAL SERVICE.

A) Select (highlight) listed user(s) and/or group(s) that you do not want to be allowed to change the time zone anymore, then click on the Remove button. (see screenshot below)
NOTE: You can press and hold the CTRL key to select more than one listed user and group.
