Are ur computer softwares original?

Some of my software are original because I didn't use licence software that must be paid.I just use a freeware which didn;t need money to get it.about my operating system,I use Microsoft Windows original,because in my place there is a cheap cd of microsoft windows from campus agreement between my campus and microsoft.the cost was so cheap.

bunch of cops will read this and soon they will knock your door and bust you

How can it be 'not original'? You mean piracy? isn't that a crime or something? I never use something like that..
