From My Portable Software:
Fast Shutdown is a Windows utility to shutdown your system. You can put this little tool on the task bar and with one click you will be able to shutdown Windows. By default Fast Shutdown will perform a safe shutdown. This means that software with unsaved works will wait for user action before closing. If you want to perform a forced shutdown, create a file called "Fast_Shutdown.ini" with this line of code: force=y and put this file in the same directory of the software.
