Information

This policy setting allows users to configure the system-wide environment variables that affect hardware configuration. This information is typically stored in the Last Known Good Configuration. Modification of these values and could lead to a hardware failure that would result in a denial-of-service condition.

The recommended state for this setting is: Administrators.

Note: This user right is considered a 'sensitive privilege' for the purposes of auditing.

Anyone who is assigned the Modify firmware environment values user right could configure the settings of a hardware component to cause it to fail, which could lead to data corruption or a DoS condition.

Solution

To establish the recommended configuration via GP, set the following UI path to Administrators :

Computer Configuration\Policies\Windows Settings\Security Settings\Local Policies\User Rights Assignment\Modify firmware environment values

Impact:

None - this is the default behavior.
