Gracefully terminate applications from powershell

closeApplication.ps1

# This script gracefully terminates all processes with the given name (first parameter) when it's run.
# It will also answer to a confirm message, if the process has one, by a given hotkey.
#
#
# signature: closeApplication.ps1 $ProcessName $ConfirmHotkey
#
#
# some simple examples how to use it:
#  closeApplications.ps1 'notepad'         close all open instances with the process name 'notepad' (you should try this)
#  closeApplications.ps1 'winword' '%Y'    close all open instances of word and and send ALT+Y if a confirmation window pops up 
#
# You are likely looking for this script to terminate software, that blocks licenses when it's not in use.
# One possibility to do this is to register this as scheduled task when locking the workstation:
#  - run taskschd.msc
#  - create a new task
#  - in trigger, add a trigger "On worksation lock" 
#  - in actions, add a new action with the following configuration
#    - Action: start a programm
#    - Programm/script: powershell
#    - Add arguments: -command "& 'C:\closeApplications.ps1' 'notepad' '(%N)'"
