As we know from the script, there are some Linux shell command in the download.py, such as 'wget', 'rm', 'rm -rf', etc. Actually, we can easily find alternative commands in windows 10. Here I summon a brief list:
wget: you can download and install wget directly from here, where you can choose *64 or *86 architecture.
rm: del (remove files)
rm -rf : rd(remove directories)
download.txt

The attachment is a modified script that works properly on windows 10. Because git do not support supply with a .py file, it has been renamed into .txt. But I am pretty sure that it works.
