Windows shutdown is a process, which prepares a system for safe power down. It means executing of some system operations, such as closing user-level applications, stopping system services, flushing disk buffers to files and sending command to hardware for switching off power. All of these operations are not simple and (if system was heavily loaded ) not fast. Windows can execute the shutdown command quickly, but this is not allowed directly from the user’s interface. In this way, user-level applications will be closed without any prompting about open files and unsaved data, and shutdown will be executed very quickly. Some cases are known, when hardly loaded systems carry out shutdown taking several minutes or even tens of minutes. On some occasions the shutdown process simply hangs and requires manual intervention. If you are sure, that you do not need to keep any data, you can apply a forced shutdown. In this case user-level applications will be closed and the system is stopped (or restarted). The system data and disk buffers will be saved correctly in any case. All these problems are successfully solved by the HSLAB Force Down program.
