Abstract
Techniques to provide a secure execution environment are described. In an implementation, a method includes initiating a hardware interrupt by an embedded controller of a computing device. In response to the interrupt, a module is executed that is stored in a basic input/output system (BIOS). The module, when executed, determines whether constrain functionality of the computing device based on a balance.
