Operating system version differences

There are no differences in the way this policy setting works between the supported on versions of Windows that are designated in the Applies To list at the beginning of this topic.

Policy management

A restart of the computer is not required for this policy setting to be effective.

Any change to the account for this user right assignment becomes effective the next time the account logs on.

Group Policy

Settings are applied in the following order through a Group Policy Object (GPO), which will overwrite settings on the local computer at the next Group Policy update:

  1. Local policy settings

  2. Site policy settings

  3. Domain policy settings

  4. OU policy settings

When a local setting is greyed out, it indicates that a GPO currently controls that setting.

Security considerations

This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation.


Changing the time zone represents little vulnerability because the system time is not affected. This setting merely enables users to display their preferred time zone while being synchronized with domain controllers in different time zones.


Countermeasures are not required because system time is not affected by this setting.
