Massively Delete Folders & Files on Windows 7 Without Prompt

I was having so much troubles to delete a folder that contains huge amount of files. Recently, I started playing with Node.JS and MEAN.js. The mean stack installed lots files (over 120MB, 17000 files) on my computer running Windows 7.

Delete lots file on Windows takes a long time and sometimes break the process and hung my computer. It, by default, removes files and it's subfolder from the folder I want to delete to recycle bin. You then have to right click on the recycle bin to clean the files.

There gotta be a simpler ways to clean files without cleaning the recycle bin.

So here are the ways to make that happen.
