Summary:In a pre-operating system environment on a device prior to loading and running an operating system on the device, a policy identifying configuration settings for the operating system is obtained. The operating system itself is prevented from changing this policy, but the policy can be changed under certain circumstances by components of the pre-operating system environment. The policy is compared to configuration values used by the operating system, and the operating system is allowed to boot with the configuration values if the configuration values satisfy the policy. However, if the configuration values do not satisfy the policy, then a responsive action is taken.
