Windows service type kernel




















The service can interact with the desktop. A service started automatically by the service control manager during system startup. For more information, see Automatically Starting Services. A device driver started by the system loader. This value is valid only for driver services. A service started by the service control manager when a process calls the StartService function. For more information, see Starting Services on Demand.

A service that cannot be started. A device driver started by the IoInitSystem function. The startup program logs the error in the event log, if possible. If the last-known-good configuration is being started, the startup operation fails. Otherwise, the system is restarted with the last-known good configuration. The startup program logs the error in the event log but continues the startup operation.

The startup program logs the error in the event log. If the last-known-good configuration is being started, the startup operation continues. Otherwise, the system is restarted with the last-known-good configuration. The display name already exists in the service control manager database either as a service name or as another display name.

The user account name specified in the lpServiceStartName parameter does not exist. The specified service already exists in this database and has been marked for deletion. Description specified by ChangeServiceConfig2. Failure actions specified by ChangeServiceConfig2.

Load ordering group specified by lpLoadOrderGroup. As we are using User Space and Kernel Space separately, so it reduces the size of the Kernel and this, in turn, reduces the size of Operating System.

As we are using different spaces for user services and kernel service, so the communication between application and services is done with the help of message parsing and this, in turn, reduces the speed of execution. It makes the use of the speed of Monolithic Kernel and the modularity of Microkernel.

Hybrid kernels are micro kernels that have some "non-essential" code in kernel-space in order for the code to run more quickly than it would be in user-space. So, some services such as network stack or filesystem are run in Kernel space to reduce the performance overhead, but still, it runs kernel code as servers in the user-space. In a Nanokrnel, as the name suggests, the whole code of the kernel is very small i.

The term nanokernel is used to describe a kernel that supports a nanosecond clock resolution. Here in this type of kernel, the resource protection is separated from the management and this, in turn, results in allowing us to perform application-specific customization. In the Exokernel, the idea is not to implement all the abstractions. But the idea is to impose as few abstractions as possible and by doing so the abstraction should be used only when needed.

So, no force abstraction will be there in Exokernel and this is the feature that makes it different from a Monolithic Kernel and Microkernel. Download Microsoft Edge More info.

The following example uses the ServiceController class to display the device driver services on the local computer.
