DShutdown is a free software that allows to quickly shutdown and wake up local or remote PCs, with many specific options. DShutdown is available for Windows system and can be used and downlaoded for free.
DShutdown supports more than just standard shutdown options, there are options relating to "pure" shutdown (such as the "force after wait" option which causes a forced, but 'clear' shutdown). There are monitoring options that allow you to shutdown a PC after a particular application terminates (useful at the end of compressing several files). There are also options to shutdown a PC when Internet traffic reduces below a particular data-rate (useful to shutdown a PC when it has finished a large download).
It is also possible to intercept a shutdown request, initiated by the user or an application, and to then execute the shutdown request with selected options from DShutdown. (For example: to simultaneously shut down all Lan PCs when the server shuts down). DShutdown doesn't force a power-off without logging off and saving settings. DShutdown instead provides a means to log-off, shutdown and safely power-off your PC. Administrators who use roaming profiles will appreciate the benefits of this feature.
