HRESULT is defined in a system header file as a 32-bit, signed integer [1] and is often treated opaquely as an integer, especially in code that consumes a function that returns HRESULT. A HRESULT value consists of the following separate items: Severity: indicates whether the function succeeded or failed
The server either does not recognize the request method, or it lacks the ability to fulfil the request. Usually this implies future availability (e.g., a new feature of a web-service API). 502 Bad Gateway The server was acting as a gateway or proxy and received an invalid response from the upstream server. 503 Service Unavailable
Service processes interact with SCM through a well-defined API, and the same API is used internally by the interactive Windows service management tools such as the MMC snap-in Services.msc and the command-line Service Control utility sc.exe.
SEH on 64-bit Windows does not involve a runtime exception handler list; instead, it uses a stack unwinding table (UNWIND_INFO) interpreted by the system when an exception occurs. [4] [5] This means that the compiler does not have to generate extra code to manually perform stack unwinding and to call exception handlers appropriately. It merely ...

In Windows NT operating systems, a Windows service is a computer program that operates in the background. [1] It is similar in concept to a Unix daemon . [ 1 ] A Windows service must conform to the interface rules and protocols of the Service Control Manager , the component responsible for managing Windows services.
An exception handling mechanism allows the procedure to raise an exception [2] if this precondition is violated, [1] for example if the procedure has been called on an abnormal set of arguments. The exception handling mechanism then handles the exception. [3] The precondition, and the definition of exception, is subjective.
This mechanism enables the automated handling of software errors independent of the application source code and of its developers. It is a direct artifact of the runtime engine paradigm and it enables unique advantages to the software life cycle that were unavailable before.
