This is so funny that it hurts. It is deadly, but to the people who read it and think about it for a second.

First you, make a bunch of folders. What's that supposed to do? That's like trying to kill a mammoth by throwing a few sheets of regular harmless paper around him.

Then, you attempt to delete a bunch of system files, which won't even work on newer systems, because it protects its files and even in unlikely case that they would actually be deleted, they can be restored.

And then... you attempt to delete whole Windows folder. Okay... think... what's odd is... Why did you even try to delete a few specific files when you're just about to delete the whole thing?

And lastly, you format the whole drive... if you're going to use that command, why even bothering with deleting specific files when this just supposedly wipes it all?

Also, you disable echo at the beginning, yet you have bunch of commands with @ in the front. Why? Why disable echo so you don't have to manually prevent echoing the commands and then you just manually prevent it anyway?

To me, it looks like you just slap a pieces of code you find without even thinking about it so here's a little advice: If you want to be come good, at anything, think about it. Think if what you're doing makes any sense, think how it works and if what you are doing has any meaning. If you think that things like making a bunch of folders make it look cool... well it doesn't for anyone who reads it and think about, it makes it look stupid and hints that you didn't give it much of a thought yourself.
