startup boost

# This can help you open the files related to the job you predefined while startup the computer, change the todolist to what you want
# change the file address to the one you're used.
# If you are using windows, press windows+R -> type: "shell:startup" -> paste the shortcup of this file (be sure you use Python as the default one to open the file)
# 簡單的小程式，幫助我這個都捨不得關機的人可以輕鬆關機，不用擔心下次啟動又要把想要的檔案或是網址再開起來一次
